When ever we face the issue of Out of memory in weblogic
following steps can be taken care
1. Check the heap size of the memory in server
2. Check the cpu and memory(%) of the server if its getting
hiked during the issue.
3. Check if there is any memory likages happening on the
server
4. Check the logs if any of the application running on the
server causing the issue like any SQL query or any
particular funcationality of an application causing an
issue.

5. Check the thread dumps in the logs.

6. If some application functionality or query is causing
the issue then the code needs to be fine tuned and even at
code level we need to make sure that objects that are
getting created are destroyed.

Through above mentioned points we can find out the root
cause of OOM and can fix it.

If the server is getting more requests we can do the
loadbalancing on the server by having disturbuted on
different ports on the same server.
