Description Casey Bodley 2019-10-10 14:33:21 UTC

Description of problem:

A data race between a frontend thread and the librados completion thread can corrupt the AioResultList and lead to segfaults. This can happen in both GET Object and PUT Object requests. Crashes reproduce more often under heavy load.


Version-Release number of selected component (if applicable): RHCS 4.0


How reproducible:

Hard to reproduce without heavy read/write workload.
