Hi,

One of the jobs running on our cluster died. After  investigating  
logs I can clearly see that job died because client that was running  
that job was evicted by MDS
Nov 14 13:31:27 node-i06 kernel: LustreError: 167-0: This client was  
evicted by ddn_home-MDT0000; in progress operations using this  
service will fail.

On MDS I can not see any messages about this client being evicted.  
There is only one message about this client:
Nov 14 13:31:27 mds01.beowulf.cluster kernel: LustreError: 22512:0: 
(handler.c:1498:mds_handle()) operation 400 on unconnected MDS from  
12345-10.143.9.6 at tcp

Can some one explain me what exactly had happened? Is this problem  
can be related to https://bugzilla.lustre.org/show_bug.cgi?id=13682

Best regards,

Wojciech Turek
