Excesive Timer warning on CentOS, qpid 0.6
I have installed qpid-0.6 broker from sources on my CentOS 5.4 box and it bugs me with excessive warnings of timer:
2010-03-30 16:26:48 warning Timer woken up 706ms late
In my previous qpid-0.5 everything was fine.
***What could cause this undesired behavior and how could I fix it?***
My build is:
boost 1.3.8
./configure --with-ssl --with-sasl

ok, you can probably ignore it, it is saying that the timer is late
which means it did not get
CPU, or the hypervisior timer/IRQ was late.
Running Qpid inside a KVM guest works very well, if in Xen what you are
seeing is the time
slicing showing through.
Timer is used for TTL, heartbeat, etc, so just don't try to set very
aggressive heartbeats and
you should be fine.

Yes it is a virtual machine for testing purposes.

Are you running on a single core box?

0-5 did not have a warning for timer overruns.

Carl gave great answers, as usual. I can add that this message was added
between 0.5 and 0.6, so that's why you didn't see it when running 0.5.
