Subject Java.lang.out.of.memory not clearly....
Date Fri, 27 Jan 2012 16:29:40 GMT
I need to know if the error is from my part (server administrator),
from the developer or from the hardware/vms. Some times that occurs
when processing two milion of registry (i am talking from expressocard
a company of credit cards).

Its a rarely error because this processing occurs rarely.

in fact, mysql in the another server with 12 processors, still
running, and tomcat in a virtual machine called adm (in another
physical machine, with 4 processors) still running.

So, this errors occurs like that:

1- Tomcat started
2- This processing is realized ok in the first time
3- Tomcat stable in the users acess.
4- The processing is realized again, some days later, inn 98% of
processing servers crashes, but mysql is still running.
5- Restar of tomcat service tomcat6 restart
6- the processing started again, and server can done the processing.

In the moment of the crash:
jstat -class
