[Lustre-discuss] ldlm_cli_cancel_req()) Got rc -108 from cancel RPC: canceling anyway

[Christopher J.Walker]

I have a stream of errors in the logs of my Lustre clients.

21544:0:(ldlm_request.c:1033:ldlm_cli_cancel_req()) Skipped 888 previous

Dec 16 15:42:33 se03 kernel: LustreError: 
21544:0:(ldlm_request.c:1622:ldlm_cli_cancel_list()) 
ldlm_cli_cancel_list: -108

We have Lustre 1.8.1.1 servers and both Lustre 1.6.7 and 1.8.1.1 clients 
(with a patch applied so we can use the 2.6.18-164.6.1.el5
  kernel).

Can anyone shed any light on what is causing them, and what I should do 
to fix them?

Chris
