Re: thread dump analysis

[Daniel Gibby]

Well, I'd rather not show the world what my java processes are doing in 
case there is something proprietary in there.

I'll send it to you personally.

I did a kill -3 on the process that showed up on top and got a stack

see what is consuming CPU.
I'm sure something must be spinning its wheels, but I don't know how to
tell... I can just see that when I run top my tomcat process has 99.9 %
of the CPU and the load average is 8.00 8.00 8.00

I'm hoping that someone can tell me what to include and what to exclude
and I'll reply with the appropriate parts of the dump.
   

Best to just post the entire dump somewhere on the web where everyone can
look at it.  Sounds like something somewhere is getting threads stuck in a
loop, should be pretty easy to spot if you get the dump during a non-busy
time.
Not sure how big of an attachment the list will accept, but you might be
able to compress it and attach it to the list.
If it's too big, just send it to me privately and I will have a look.
