[LU-12464] sanity test 51f still periodically runs out of memory with zfs backend

• Status: Open
• Project: Lustre

Description

Alex commented in LU-9514 that he still sees it too.

For me client has 4G RAM and is a separate node so this should not really be happening.

It's far from 100% but does happen from time to time nevertheless and apparently only on ZFS, so I am opening a separate ticket for it.

apparently happens in maloo as well, and again in ZFS only. https://testing.whamcloud.com/test_sets/1c85b7d6-82cb-11e9-be83-52540065bddc
