Subject Re: is there any way to auto recover the wasce server?
Date Fri, 10 Apr 2009 07:13:01 GMT
I'd say it's not a good idea to restart the server to clean up things.

If it's the performance becomes unacceptable because there are too many
users and the server is overloaded, then you should add more servers to the
cluster to distribute the workload, or upgrade the hardware configuration of
the current server (more memory, more CPU, etc.).

If there are memory leaks (as you say the memory consumption gets larger and
larger), you should check whether it's a problem in your application (e.g.,
not releasing objects in time). It might also be a problem in the server,
for which people here are happy to work with you to solve.
