FATAL ProcessRunner - Unexpected EOF from process runner child!
ild killed by signal 1510-24-2014 06:42:23.633 -0600 ERROR ProcessRunner - helper process seems to have died (child killed by signal 15: Terminated)
There's a possibility that, instead of using splunk restart/stop/start, splunkd is used which is a daemon itself.
Signal 15 is sent to a process by the Linux kill command. Is it possible that someone killed the process?
As per logs nobody kills it manually still looking for the reason...
This also occurred on the indexer level but instead with a signal 9 in splunkd.log for version 6.0.5, is this known issue?
