All
On Linux 64 bit machine and weblogic 10.3.2 we are getting OOM very frequently.
I have used MissionControl to see if there is any JavaHeap issue but I could not find any. I notice there is a constant increase in physical memory usage where as the
Java Heap usage was increasing and decreasing at regular intervals(GC).
Thanks in advance for your help.
Below are the details for hardware and appserver startup params
