around the problem:

on of solution is :
-- cut --
now I use jdk1.3.1_06 with hospot -server
and it works perfectly (and faster)
-- end cut ---
another one was a hardware problem:

 Some part
of the computer seemed to be not compatible with the
FSB133 standard. So I reduced the system to FSB100.
No signal 11 since that time :-

and here another issue with java:

In this case, it was happening during the compilation of a reasonably
large JSP. A colleague found out that there was a known issue with
this version of javac compiling large methods (>64Kb), which tends to
happen when you have a large JSP getting compiled into a single
service() method.

Subject: JVM Crash

Hello all,
I deployed Atlassian Jira Enterprise 3.0.3 in Tomcat 5.0.28 and I 
experienced two random JVM crashes in a period of one month. The
strange 

part is that the crashes occured when the application was at a
very low 

load, doing almost nothing.
I searched the archives for this topic, but I still can't figure
out 

what could have caused these crashes.
I have no idea whether they are related to Jira, Tomcat, J2SDK or 
RedHat. I would like to isolate the problem, so that I can ask the

proper vendor for support.
Below I will post information about my system and the JVM error
logs, 

sorry for the long message.
Any help is greatly appreciated, thanks a lot.
Rodrigo
