[ovirt-devel] [ OST Failure Report ] [ oVirt Master (ovirt-engine) ] [ 27-03-2018 ] [ 004_basic_sanity.disk_operations ]

[Benny Zlotnik]

This issue looks like it's caused by the DB lock being released before the
engine memory lock, there was a similar race with the LSM test a few months
back. I'll apply the same fix for the snapshot_cold_merge.
