Hi Zheng,
Sorry - I've just re-read your email and saw your instruction to restore
the mds_cache_size and mds_cache_memory_limit to original values if the

For the question of OSD failures causing MDS crashes, there are many

Yes, Zheng's fix for the MDS crash is in current mainline and will be
in the next Firefly RC release.
Sage, is there something else we can/should be doing when a client
goes to sleep that we aren't already? (ie, flushing out all dirty data
or something and disconnecting?)
