      I have a photo which is around 3 MB that I'm trying to PUT to an external process on the CouchDB database. The external process is called "_upload".
      I get an uncaught error "{exit,{body_too_large,content_length}}" in the logs when trying this. Smaller photos (around 60 kB) seem to work just fine.
      This just happens with external processes. I can upload the photo as an attachment directly to a document, with no problems.

      The error is similar to an earlier bug in the mochiweb library that was fixed around Feb 2009, where mochiweb never used the "max_document_size" setting that was provided when calling mochiweb_request:recv_body.

      I believe, supported by the stack trace below, that the cause for this bug is that in couch_httpd_external:json_req_obj the function mochiweb_request:recv_body/0 is called, which uses the mochiweb default value on MaxBody, which is 1 MB.
      I think that couch_httpd_external:json_req_obj should call mochiweb_request:recv_body/1 instead, with the "max_document_size" setting as the argument.

      Here are the error logs from one of my attempts:
