Hi,
On 6.2 (2.6.32-220.23.1.el6.x86_64) I noticed that qpidd started to use an
enormous amount of cpu time. It is probably related to the last leap second.
Doing an strace I saw it doing futex() calls in a furious rate.
After doing the
export LANG=C
date; date `date +"%m%d%H%M%C%y.%S"`; date
trick and restarting qpidd, the problem was gone.
I'm not sure exactly what caused it, but I noticed the same thing on one
of my machines. It turns out I no longer needed the package that had
brought qpid along with it anyway (Matahari), but the problem was
exactly what you describe.
On another note, however, Firefox now completely consumes one
processor's time any time it is started, even with scripting and all
plugins removed. This is worse than the qpid problem because Firefox
isn't set to a lower priority level, so it is really noticeable on
lower-power systems with only one or two processors. Thunderbird also
now chews up a lot of CPU time, but it is intermittent, not constant the
way Firefox is.
