Hi Experts,
We have been facing heap memory issue on SAP Web AS server suddenly from the past 4 days. The Full GC that is been triggered is not able free any space from Tenured generation. So system generates lot Full GC's continuously and finally signals for a system shutdown.
We tried analyzing the OOM dump that got created using the Ecclipse Memory Analyzer tool suspecting some memory leaks:
Though we got some results from MAT unfortunately we are not that equipped to understand what exactly is going wrong as per MAT results. Could someone please help what can be done for the Full GC to function properly and avoid leaks if any ?
Thanks in Advance !!
Hello,
You can check GC history using SAPJVM profiler and check the GC report. TO trigger history use the note # 1995856 - How to retrieve the complete GC history
and you can analyze this using SAPJVM profiler (https://wiki.scn.sap.com/wiki/display/ASJAVA/Java+Profiling)
Regards,
Asha
