[otrs] OTRS6 Database Crash Due to Memory Loss
Johnnie Rucker
Community,
We are currently running on the version otrs-6.0.14-01.noarch. We are getting weekly crashes where the database locks up due to being out of memory. Is this happening to anyone else? Is there a possible fix to this issue?
Current set up
OS: Cent OS 7.5
Memory:12 GB
Database:
MariaDB-compat-10.2.18-1.el7.centos.x86_64
MariaDB-client-10.2.18-1.el7.centos.x86_64
MariaDB-common-10.2.18-1.el7.centos.x86_64
MariaDB-server-10.2.18-1.el7.centos.x86_64
OTRS version
otrs-6.0.14-01.noarch
Issue:
DB locks up, CPU locks up. Once DB is restarted, app is fine
[1311431.213740] Out of memory: Kill process 8902 (/opt/otrs/bin/c) score 5 or sacrifice child

Happens once a week
Thank You,

The kernel’s Oom killer is usually a good indicator that either you should add more memory or you the configuration needs to be adjusted. I had the experience most of the time with Apache’s httpd or the database. Did you have some kind of resource monitoring regarding the memory consumption of the specific services?
Kind regards,
Roy
