      Our MDS server crashed due to memory exhaustion. Examination of the system logs show nothing out of the ordinary expect it was noticed that an IO scrub did start off on the MDS server:

      Lustre: atlas1-MDT0000-o: trigger OI scrub by RPC for the [0x20003f37b:0x3e5:0x0] with flags 0x4a, rc = 0

      Some time after that we encountered the following crash which is attached.
