      Description

      Having 3 Couches all replicating a couple of databases to each other (pull replication with a update notification process) the HTTP service on any of the Couches stops working at some point (when running for a couple of ours with constant changes on all databases and servers).

      This is the error when a new HTTP request comes in:

      =ERROR REPORT==== 19-Oct-2009::10:18:55 ===
      application: mochiweb
      "Accept failed error"
      "

      {error,enfile}

      "
      [error] [<0.21619.12>] {error_report,<0.24.0>,
      {<0.21619.12>,crash_report,
      [[{initial_call,{mochiweb_socket_server,acceptor_loop,['Argument__1']}},

      {pid,<0.21619.12>}

      ,

      {registered_name,[]}

      ,
      {error_info,
      {exit,

      {error,accept_failed},
      [{mochiweb_socket_server,acceptor_loop,1},
      {proc_lib,init_p_do_apply,3}]}},
      {ancestors, [couch_httpd,couch_secondary_services,couch_server_sup,<0.1.0>]},
      {messages,[]},
      {links,[<0.66.0>]},
      {dictionary,[]},
      {trap_exit,false},
      {status,running},
      {heap_size,233},
      {stack_size,24},
      {reductions,202}],
      []]}}
      [error] [<0.66.0>] {error_report,<0.24.0>,
      {<0.66.0>,std_error,
      {mochiweb_socket_server,225,{acceptor_error,{error,accept_failed}

      }}}}

      To me this seems like it runs out of threads or sockets to handle the new connection or somewhat like this.

      Also i see in this setup that if i put lots of changes in a short time at some point the replication process hangs (never finishes) and when trying to restart the same replication once again is not possible and resulting in a timeout.

        does this still happen with 0.11.0 or turnk?

        All right i got this issue again on one of the nodes in the cluster. The software is now CouchDB 1.1.0 with Erlang R14B02.

        After a couple of hours replicating from 3 other nodes and constant changes on the local node it stopps accepting HTTP (see error below).

        I have checked with netstat and also saw lots of connections using the CouchDB port.

        It only happens on one node on the cluster though. I keep monitoring if that happens every day. I had a similar issue (replication did hang at some point) but thought this to be related to stunnel as there was no trace in the couch. Yesterday i have switched to native CouchDB SSL and now there is this trace.

        Looks like it run out of file handles?

        If netstat showed lots of connections (which consume file handles, too) , this could be related to COUCHDB-1100?

        I had this again last night and did some further checks and found that there were around 800 sockets in CLOSE_WAIT state for couchdb process. Though this does not seem to be related to COUCHDB-1100 as i do not have any large views which timeout while updating.

        All right, got some statistics data. Looks like that some service crashed and was restarted. After that point, it ran wild for a couple of hours and then stops responding. When looking at the image which basically counts the number of various http responses for the Couch from _stats. The first big drop of numbers was the crash. The second drop was the manual restart. Between these two, it seems to loose file pointers.

        I have uploaded several graphs, showing a single crash event after which it starts to act crazy and seems to run out of file pointers.

        Think I've hit the same thing in 1.2.0. After making lots of view queries (triggering a reindex on every one on the server with a script) the server got into a state where it would abort a random selection of requests (made at a more leisurely rate), including a number of those used by Futon. Didn't have a chance to investigate socket states on the server unfortunately.

        The first error was this:
        [Wed, 09 Jan 2013 16:00:03 GMT] [error] [<0.1528.3109>] {error_report,<0.32.0>,

        Lots of these:

        I can confirm that this still happens in couchdb 1.6.0. I believe that it the error that is produced as a result of following the procedure outlined in COUCHDB-1100

        Clement Law added a comment - I can confirm that this still happens in couchdb 1.6.0. I believe that it the error that is produced as a result of following the procedure outlined in COUCHDB-1100 Here's an example of the type of error I get: {error_report,<0.31.0>, {<0.4535.96>,crash_report, [[{initial_call, {mochiweb_acceptor,init, ['Argument__1','Argument__2','Argument__3'] }}, {pid,<0.4535.96>} , {registered_name,[]} , {error_info, {exit, {error,accept_failed} , [{mochiweb_acceptor,init,3, [ {file,"mochiweb_acceptor.erl"} , {line,34} ]}, {proc_lib,init_p_do_apply,3, [ {file,"proc_lib.erl"} , {line,239} ]}]}}, {ancestors, [couch_httpd,couch_secondary_services, couch_server_sup,<0.32.0>]} , {messages,[]} , {links,[<0.105.0>]} , {dictionary,[]} , {trap_exit,false} , {status,running} , {heap_size,233} , {stack_size,27} , {reductions,276} ], []]}}

        Have you tried to tweak mochiweb acceptor pool? Like:

        [httpd]
        server_options = [{acceptor_pool_size, 256}]
        

        It's 16 by default, so it much likely that you have pool limit reached by accepted connection and yet another one causes the failure. I tend to think that this is "default config problem" issue.

        I tried this, and I still get the same errors. I'm not really certain if this a bug after all. I'm basically DOSing the couchdb with web requests, so eventually it fills the sockets. It recovers well enough after the DOSing finishes.

        How this "DOS" works? Do you have a script to reproduce the issue for everyone?

        It's the instructions outlined in COUCHDB-1100, but with a changed wget timeout:

        while true; do curl -m0.01 'http://127.0.0.1:5984/grande/_design/testviews/_view/byDate1?limit=1'; done

        Clement Law hm...I run your script with 3 processes against view index for 7 million records. After 20 minutes CouchDB still up and all I see is around 30-40K connections in TIME_WAIT / CLOSE_WAIT, but they getting closed operatively so no overflow happens. As for cold index I certainly got an error about reaching system limits since all these flood connections are awaiting for view build.

        Have the following config on Gentoo Linux 3.16.5 with CouchDB 1.6.1:

        [httpd]
        socket_options = [{recbuf, 262144}, {sndbuf, 262144}, {nodelay, true}]
        server_options = [{backlog, 4096}, {acceptor_pool_size, 256}]

        Alexander Shorin added a comment - Clement Law hm...I run your script with 3 processes against view index for 7 million records. After 20 minutes CouchDB still up and all I see is around 30-40K connections in TIME_WAIT / CLOSE_WAIT, but they getting closed operatively so no overflow happens. As for cold index I certainly got an error about reaching system limits since all these flood connections are awaiting for view build. Have the following config on Gentoo Linux 3.16.5 with CouchDB 1.6.1: [httpd] socket_options = [{recbuf, 262144}, {sndbuf, 262144}, {nodelay, true }] server_options = [{backlog, 4096},

        Looking on James Howe error log I noticed `enfile` which means that file table overflow (http://www.erlang.org/doc/man/file.html scroll to POSIX error codes). Not sure in details what does it means, but it looks like lack of available resources on host system. Don't you have the same?

        open files (-n) 1024

        If you're DOSing a server you'll hit this limit in first place: couchdb user is only able to serve 1024 file descriptors which roughly means it will accept only ~1000 connections before fail.

        Yes, what I have decided to do for now is to increase the maximum of open files to something larger (2048 etc). The most desirable thing to have is for the client making the request to be able to tell the server how long it will wait around for before giving up. That way, the server can know how long to run a process for before giving up. Currently, the server doesn't know whether a client is still waiting for a reply until it tries using the socket.

        2048 is to small too. Even single while curl process produces 10K active connections. Though, you better configure this according your setup. On second, in your program you can tell your http client how long should it wait for a response and curl also has option for that. On your system you may also configure how long it will serve TIME_WAIT connections before close them. Server actually monitors inactive connections and drops dead ones - iirc mochiweb has 30 seconds timeout for that, but if they're running with keepalive on, certainly, they will say active for a much longer time.
