Description

hi,

i'm seeing following messages from 2.4.2 OSS every few minutes:

surprisingly, the errors are spewed only from two OSSes out of the lot and only for specific OSTs.

at the same time MDS is throwing following:

these errors are seen after all the servers have been rebooted afresh as part of maintenance cycle (some other LBUGs were fixed).

any pointers what could be causing it?
