error)

Key: AMQ-1873
URL: https://issues.apache.org/activemq/browse/AMQ-1873
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 5.1.0
Environment: Linux RHEL 4
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Server VM (build 1.5.0_15-b04, mixed mode)
Reporter: Julien Devemy

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.net.PlainSocketImpl.socketAccept(Native Method)
at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:384)

org.apache.activemq.transport.tcp.TcpTransportServer.run(TcpTransportServer.java:221)
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.
