[Pvfs2-users] Error messages on client and server

[Murali Vilayannur]

Hi Trach,
Hmm.. are you experiencing any I/O failures as a result of these?
It looks like some I/O timeouts may have caused the cancellations in
the flow layer or something.. I think Sam or Phil may have something
more insightful to say than me..
thanks!
Murali
