Patch has landed and the time 64 work fixed the problems.

This Ben thinks this might be a 64 bit timer issues I linked it to LU-9019.

[Andreas Dilger]

This hasn't been seen because the test is currently always being skipped.

[Peter Jones]

Has not been seen in many months

Hm. Looks like I need to push a patch for cleanup the time wrappers.

[Ben Evans (Inactive)]

Just ran into this (or something quite similar) on a 2.5.2 build

I think the ldlm_pool_recalc may help, but I also noticed that internally ldlm_pool_recalc is working with time_t, and returns an int. I'm wondering if there are 32/64 bit issues here. In my case, I know time_t is 64 bit, and int is 32 bit.

so if you run with increased debugging where you can trace by rpc xid to see what happened with that request? could it bemds replied and client missed it? unplausible, but a start to see what's going on.

Actualy that's only in console logs that there's no lfs, but in syslog the lfs is there which is pretty strange.
MDS still appears to be totally idle.
