[vikas_gopal]

Hello Splunk ES experts ,

My Splunkd is crashing frequently with below error in crash logs

C++ exception:
exception_addr=0x7ff2c2c3c620
typeinfo=0x556c38241c48, name=St9bad_alloc
Exception indicates memory allocation failure

This started after ES app installation . I have checked with free command I have plenty of  memory on the system 32GB and 16 CPU

               total                 used            free                   shared           buff/cache           available
Mem: 32750180     1764936    19979208     17744               11006036         31040488
Swap: 4169724          0                   4169724

Below are my ulimit settings
