Hi All,
Suddenly, the environment became very slow and then completely inaccessible. Upon checking the Tomcat logs on the server, we discovered an OutOfMemory error. We later found out that performance testing had been conducted in this environment, which is not intended for load testing.
need some help to recover the environment
Thanks in Advance ,
Udhaya

I am not an expert in on-premise maintenance but I heard you need to clear the cache (KAFKA , HS, SS) and need to restart your environment.

We have determined that the issue was caused by a heap memory problem. An expression with a database call had a batch size of -1 and was running in a loop, which led to the heap memory being exhausted and ultimately caused the application to crash.
