      Description

      I'm actually testing ActiveMQ with a python stomp Client (stomp.py http://www.briggs.net.nz/log/projects/stomppy/).

      I'm trying to load the broker with ~200 producers (on ~200 hosts) feeding one TOPIC for only one consumer.

      Everything is working almost fine until the client connection fails.

      The ActiveMQ log displays :
      ...
      2008-07-30 09:28:43,665 [localhost:61613] ERROR TransportConnector - Could not accept connection : Too many open files
      2008-07-30 09:28:43,665 [localhost:61613] DEBUG TransportConnector - Reason: Too many open files
      java.net.SocketException: Too many open files

      at java.lang.Thread.run(Thread.java:595)

      When I look at the open files (or connections) (with lsof) I see 65446 lines like :

      java 26765 root *066u sock 0,4 7534034 can't identify protocol

      This seems to indicate that ActiveMQ doesn't totally released the UNIX socket

      I'm attaching the activemq.xml conf file.
