How do I start Splunk after it stopped responding with ERROR ProcessRunner?

[abhijitnath89bm]

I received the below error. Now, none of the Splunk start or stop commands are responding. Please let us know how we will bring Splunk back to life.

03-01-2019 09:05:15.702 -0500 FATAL ProcessRunner - Unexpected EOF from process runner child!
03-01-2019 09:05:15.702 -0500 ERROR ProcessRunner - helper process seems to have died (child killed by signal 15: Terminated)!

The linux OOM (out-of-memory) killer probably killed the Splunk search process. You should run this command to see if the OOM killer is occuring:

dmesg -T| grep 'illed process'

If this returns results it means you don't have enough system memory for what you are trying to do.

All the best.
