We have recently started experiencing issues with Sympa crashing. Logs will indicate memory cannot be allocated. Memory usage on the system during the crashes will often be 85-90% used.

Here is the log line from the latest crash:

Dec  7 17:25:09 list-app sympa_msg[1787]: err main::#243 > Sympa::Spindle::spin#95 > Sympa::Spindle::DoForward::_twist#186 > Sympa::Mailer::store#160 > Sympa::Mailer::_safefork#255 DIED: Exiting because cannot create new process for <address@concealed>: Cannot allocate memory at /usr/share/sympa/lib/Sympa/ line 255.

Line 255 in is the die statement inside of the ‘safefork’ subroutine [1].

We are running Sympa 6.2.64 on CentOS 7 and we have 8 GB of RAM allocated to the system.

Do you have any graphs of memory usage? Like grafana or munin?
Our sympa install uses quite a bit all the time, plus there are all the system caches, etc. I suspect 8gb might be limiting you, but a graph would probably show for sure.

Attached an example of ours.
