1. Re: 'hornetq-buffer-timeout' thread: huge CPU time. Is it normal ?
jbertram Apr 14, 2014 9:53 AM (in response to icemaker)1 of 1 people found this helpfulIO for the HornetQ journal is done through this thread so it should be used often, but I can't say with certainty what the ratio of CPU time vs. server run time should be.
In any case, the version of HornetQ you're using is fairly old so I would recommend upgrading whenever possible. org.hornetq.core.journal.impl.TimedBuffer in particular received an optimization since 2.2.13.Final (see 2f949ed940d226a6afe031686253023dccbc4155 on master).
Can you describe exactly what you mean by "After about 4 hours our server runs extremely slow"?

2. Re: 'hornetq-buffer-timeout' thread: huge CPU time. Is it normal ?
icemaker Apr 15, 2014 9:16 AM (in response to jbertram)Thanks for your answer
Well all processes are suddenly running extremely slow and we don't really know why. CPU usage seems ok, Memory usage is also ok.
So we suspected a blocking thread somewhere but could not find one.
I'll try to update HornetQ.
Do I just need to update HornetQ jars in Jboss AS 7.1.1 modules or is there something more to do ?

3. Re: 'hornetq-buffer-timeout' thread: huge CPU time. Is it normal ?
jbertram Apr 15, 2014 9:46 AM (in response to icemaker)You can try updating the HornetQ jars in JBoss AS 7.1.1, but I'm not 100% sure that will work. You may hit an incompatibility somewhere. You might look at WildFly 8.0.0.Final or 8.1.0.CR1 or perhaps JBoss EAP 6.x which is built using later versions of AS 7.1.x.
