KV Store Fails about once a week

[AJSCSA]

Roughly once a week, I'm getting the following errors on my single instance Splunk deployment.

KV Store changed status to failed. KVStore process terminated..
12/3/2020, 11:53:25 AM

KV Store process terminated abnormally (exit code 14, status exited with code 14). See mongod.log and splunkd.log for details.
12/3/2020, 11:53:25 AM

Now, I can fix the issue, by stopping Splunk, renaming the mongod folder and restarting Splunk but I want to know why I'm getting the errors and how to prevent them in the first place.  Any help or assistance would be greatly appreciated.

Hi @AJSCSA,

These alerts you have referenced in your post, is this the "alert" that pops up when you log into the Webpage?

Can you provide some output as to what the following log shows with lines that pertain to KVStore?

On Linux:
# tail -f /opt/splunk/var/log/splunk/mongod.log

On Windows:
# type /opt/splunk/var/log/splunk/mongod.log
OR
# Get-Content /opt/splunk/var/log/splunk/mongod.log -wait

Do let us know what the results yield!

V/R,
