    Description

      ExeMgr can go out of allowed memory limits doing sorting.

      Try to sort unreasonable amount of records that and instead of an error the system goes swapping then crashes or got killed by OOM.

      The intermediate workaround is to apply dedicated cgroup rules to ExeMgr.
