Subject: 2.6.5-pre TCP connect problems
Date: Mon, 29 Mar 2004 15:50:42 +0200	[thread overview]
Message-ID: <20040329135042.GG2992@suse.de> (raw)

Hi,

I'm currently debugging a problem with TCP reconnects in 2.6.5-pre where
the TCP reconnect code got rewritten to use worker queues.  What happens
is that the NFS server drops the connection immediately and that state
change isn't propagated to the transport. The typical sequence of
events goes like this

Mar 29 15:44:00 e36 kernel: RPC: 28611 call_transmit (status 0)
Mar 29 15:44:00 e36 kernel: RPC: 28611 xprt_prepare_transmit
Mar 29 15:44:00 e36 kernel: RPC: 28611 call_status (status -107)
Mar 29 15:44:00 e36 kernel: RPC: 28611 call_bind xprt d42c4200 is not connected

Does this sound familiar to anyone?

Olaf
