[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Clients Hanging...

[clebert.suconic@jboss.com]

When I run the perfSender (without perfListener) it's very common the client hanging without an answer.

The client keeps waiting on this condition, as if a message was dropped on the wire.

 [java] "main" prio=1 tid=0x000000004011d620 nid=0xa70 in Object.wait() [0x00007fff4bbc1000..0x00007fff4bbc2190]

  |      [java] 	at org.jboss.jms.example.PerfExample.main(PerfExample.java:74)
  |      [java]

This happens on Persistent or NonPersistent messages. Allthough on NonPersistent messages it would happen more frequently.

Any idea why?


I may do some research on this later (maybe monday). But maybe this is known issue.
