Question : Memory problems in Weblogic

We are using Weblogic 8.1 on Solaris 8. The web site is intermittently not available.The bad part is we do not have a genuine exception handling and thus not able to find the actual reason for this error from our logs.

Restarting the server is solving the problem for a day but the issue appears the next day again.There are lot of memory leaks in the application , and we manual force garbage collection twice daily.

The memory details were provided to us but I am not really sure ,how much memory is eaten up and if we need to add new memory.

These are the details I can provide. Can anyone help me and say if it is an issue with the memory and the solution.

Answer : Memory problems in Weblogic

try increasing the number of default threads that might be able to solve your problem.
we have seen something similar . if not solve your problem it will increase the time period within which your website will hang.also capture thread dumps and the hardware usage at the time when your application hangs/unavailable.
you might have to use a profiler to pin point the method which causes the memory leak in case increasing thread count doesnt help.
