Could you please help on the below issue?
We have got Application out of memory incident. From the description, we could see the issue is heap size. Please suggest us how to find out the root cause for heap size and associated transactions?
Customer is more interested in knowing the transactions that are causing increase in heap size.
You have to do memory analysis by following the below tutorial, this will help you in finding the issue
Note: While doing Memory Leak Analysis make sure confirming with the application team, as it suspends the application while you are performing this. I mean application will not be accessible, also you should need the Analysis server component running and connected to the AppMon server for post processing the captured data through this analysis.
Also, please go through this Online Perf Clinic - Memory Diagnostics for Java & .NET https://youtu.be/SWy83EW_xhk tutorial by @Andreas G. which is a good one to start and gives you a overview on the memory.
