Posted: 1 year agoRachit_Agarwal PEGA replied to NickM591Hi NickM591, GC overhead limit exceeded" indicates that the garbage collector is running all the time and Java program is making very slow progress. You can do the following. Increase the heap size if the current heap is not enough. Use memory profiling tools like MAT ( Memory analyzer tool), Visual VM etc and fix memory leaks. Apart from setting heap memory with -Xms1g -Xmx2g , try -XX:+UseG1GC -XX:G1HeapRegionSize=n -XX:MaxGCPauseMillis=m -XX:ParallelGCThreads=n -XX:ConcGCThreads=n Posted: 1 year agoNickM591 Contra Costa County replied to Rachit_AgarwalHi Rachit, I have updated the arguments based on your suggestions and it did not help. I suspect Pega is failing somewhere and impacting the application server. Thanks.
