[ovirt-users] Delete snapshots task hung

Hi Everyone, I'm waiting since 3 days for 5 x delete snapshot tasks to finish, and for some reason it seems to be stucked.For other vms snapshot removal took at most 20 mins, with havin the disks pretty much same size, and snapshots numbers. Any thoughts on how should I get this fixed ? Below, some lines from the engine.log, and it seems to show some complains regarding locks ( Failed to acquire lock and wait lock) , although I am not sure if thats the root cause: Thank you very much !
