Subject ActiveMQ 5.0.0 OutOfMemory
Date Mon, 03 Mar 2008 21:43:19 GMT

Hi,

when running activemq and I connect to it with a client I get the following
exception or exceptions?

java.io.EOFException

But one thing i have noticed is that when I run AMQ on this particular
machine i get up to 36 activeMQ processes...(this is prior to any
connections) where on the other 4 systems It runs on there is only 1..

I have tired to fiddle with the JVM memory stack thingies but with no lock
(increasing, decreasing etc) and its not a file descriptor restriction issue
(its set to 65536)

any ideas?
