Dear,

Just before crash below message logged into system logs of servers:

Jun 11 23:01:37 musang kernel: Out of memory: Kill process 22184 (slapd) score 888 or sacrifice child

Jun 11 23:01:37 musang kernel: Killed process 22184, UID 0, (slapd) total-vm:52226320kB, anon-rss:37170216kB, file-rss:1044kB

Although, my physical RAM size is 38 GB & actual database size is 32 GB.

Why is it not managing memory appropriately with the help from swap...?

----

Thanks & Kind Regards,

Saurabh LAHOTI.
