Description
When doing a lot of of update operations, mongod processes randomly crash (not always, not often).
This is a development shard server (with core sharding) :
- 3 shards of 3 members each (Primary, Secondary, Arbiter)
- Data / Journal / Log are on separated disks, all mounted with LUKS filesystem
I suspect LUKS to be the source of the problem.
The running updates are using $addToSet / $elemMatch.
I attached the error information and backtrace, let me know if you need more info.
