Subject ActiveMQ log question
Date Thu, 25 Aug 2011 20:41:24 GMT
Hello, 

Sorry for the repost I don't think I was subscribed properly with my
previous attempt.

I have a question regarding some messages that are appearing in the
activemq.log and what they actually mean.  I've recently setup a server
running AMQ5.5.0.  I've got stomp+nio setup as the transport connector.  And
I'm using Hiram's benchmark tool to put it through it's paces.  I turned on
the DEBUG log to get more information, but I can't figure out why I'm
getting the EOFException or the IOException.  It looks like things recover
just fine.  But I can't shake the feeling that something is happening that
shouldn't be happening.  Or that maybe messages are being dropped.  Any
ideas on configurations that I could tweak to handle this?  Am I even
interpreting the log correctly? 

Thanks 

Rishi
