            I tried again this morning with 2.10.5 and it seems to be working without the patch so we can close the bug.

            I think I still had the issue even with the patch from LU-5020.  I'll try to verify that in a the next day or two.

            Is the patch https://review.whamcloud.com/10229 "LU-5020 llite: don't reconnect MGC if connecting" enough to fix this problem, or is https://review.whamcloud.com/26839 still needed?

            I believe this issue will affect master but the only system I have to test on was 2.5.3.
