Hi ,

In our Splunk environment, standalone search head is going down often.
Could anyone , what would be the reason on this?

When i check SH internal logs,at time just before down time . I could see the below errors

Hi mala_splunk_91,
it's hard to debug a problem likethis!
what Linux are you using? see on internet if there are known issues on this Operative System.
Anyway, I suggest to open a case to Splunk Support because the only way is a webex to see you installation.
Bye.

i know it's old thread ,i assume it helps ,
once check DMC on your search head , and go to "resource usage: instance"
check for Maximum Physical Memory Usage by Process Class& Maximum CPU Usage by Process Class
identify which process class consuming more resources , usually it is "search activity" in my case
