[Gluster-devel] ping timer expired! bailing transport

[Dan Parsons]

I just received this error message using rc4:
2009-03-09 21:58:16 E [client-protocol.c:505:client_ping_timer_expired]
distfs03-stripe: ping timer expired! bailing transport
2009-03-09 21:58:16 N [client-protocol.c:6607:notify] distfs03-stripe:
disconnected

It happened a total of 7 times across my 33 client nodes. It doesn't seem to
be related to any particular client, but the errors did happen mostly
(though not always) on the unify-ns server. The gluster servers are under
pretty heavy network utilization, however it doesn't seem to be near the
link capacity and in any case, i/o should just block if it's slow to
respond, correct? Fortunately, gluster is automatically reconnecting after
the error. I don't remember seeing this in rc2. The only corresponding
errors in the server logs are simply showing the client disconnecting. I've
also ruled out any interconnect faults.

Any suggestions? My configs are below.
