Hello,
This is a follow up from last week, the server seemed to have the same
issue, where it was over running to 75%.
Using top (centos 6) there seemed a lot of java threads, the the top thread
was 15209 >> 0x3b69
These are the start options. I increased -Xmx buy 256m to 768m since last
week

Cheers Greg

The pollerThreadCount applies only to the HTTP version of

I have had a look and I cannot find where this is set. Is there any
documentation on this?

Thanks, I am going to up the memory. The profiler I used only highlighted
the ajp-apr-8009-Poller as active. Terminating the thread stopped the high
cpu.

Not the whole story. A small part of what was in PermGen is now allocated in
the Java heap, but the majority is moved to
Thanks for the reply, I will up the memory on the heap space and have
another go with the profiler if happens again. When I was looking at the
thread dumps there were no other active threads other than the
ajp-apr-8009-Poller so maybe it is only a memory issue.
Cheers Greg.

Hello,
After an upgrade to Tomcat 8.0.21 and (Oracle jdk1.8.0_40) I seem to be
having an erratic high cpu issue, often when the server gets busy. The
application was OK tomcat 7 and has not been modified since the upgrade.
I use mod_jk / apache
