Subject Too many open files using ActiveMQ 5.4.1
Date Wed, 07 Sep 2011 08:22:19 GMT
I have an AcitiveMQ broker 5.4.1 running on Ubuntu server with 700 clients
connected via openwire and less then a minute after starting the server I am
receiving many exceptions:

2011-09-07 11:15:24,911 ERROR TransportConnector:234 - Could not accept
connection : java.net.SocketException: Too many open files [{ActiveMQ
Transport Server:
tcp://0.0.0.0:61616?wireFormat.tightEncodingEnabled=false?jms.prefetchPolicy.all=50}]
2011-09-07 11:15:24,911 DEBUG TransportConnector:236 - Reason:

        at
org.apache.activemq.transport.tcp.TcpTransportServer.run(TcpTransportServer.java:279)
        at java.lang.Thread.run(Thread.java:662)

This problem reproduces easily ( every restart ).

Any idea why this is happening or how can I find the source of the problem ?
