Hi,

My MDS is very slow, and it logs stuff like this:

2014-11-07 23:38:41.154939 7f8180a31700  0 log_channel(default) log
[WRN] : 2 slow requests, 1 included below; oldest blocked for >

[WRN] : slow request 121.322570 seconds old, received at 2014-11-07
23:36:39.832336: client_request(client.7071:115 getattr pAsLsXsFs
#1000002bdbe 2014-11-07 23:36:39.000000) currently failed to rdlock, waiting

Any idea what that rdlock is and what might cause it to fail?

This is on Giant by the way.

Thanks,

Erik.
