the load average in the server increases to 20.00 , the load
decreases only when we stop or restart the tomcat . what could
be the reason and how to solve this issue.
pls help me.
I used to work a lot on Tomcat servers--major mission-critical transaction-oriented financial application--not as a developer, but as a sysadmin. You will probably want to use a memory profiler to determine what is eating up system resources. See:
...for information on memory profiling.
Many versions of Tomcat are buggy and have memory leaks. 4.1 is QUITE old also (2 years?). You might consider upgrading to the 5.5.x series, though test it carefully first as you might get incompatibilities or conflicts with new jars.
As an aside, this is not a problem you should be concerned with if you are the sysadmin. Developers should be aware of and know how to use debugging tools.
