#137 osci-jenkins instances have only 4 gigs of memory
Closed by astepano. Opened by msrb.

It seems like https://osci-jenkins-1.ci.fedoraproject.org/ Jenkins is running with only 4 gigs of memory. This was fine last week when the highest load was ~200 concurrent builds, but this week we enabled also rpminspect and dist-git pipelines there. And there were 600 builds running at the same time, which killed the instance (I am not surprised personally). 

$ cat /sys/fs/cgroup/memory/memory.limit_in_bytes
4294967296
$

Since 4 gigs of memory is probably a default value from Jenkins helm chart that was used to deploy the instance, it is possible that number of CPUs is also quite low.

Note https://osci-jenkins-2.ci.fedoraproject.org instance is affected by these quite low resources limits as well.

cc @bgoncalv as he has jobs running on the second instance

@astepano @jimbair which one of you fine folks would be able to increase the resource limits on those instances? :)
