[LU-7378] Error destroying object with RC115

Description

We are encountering an issue on our lustre-2.5.4+ servers where we are seeing an error destroying objects with RC115, then the OI scrubber is starting. We suspect that the OI scrubber may be causing some jobs to run over wallclock.

I have attached some kernel logs, and below is the output from the OI scrubber:
