[OpenAFS-devel] "Lost contact with file server" problems

[Harald Barth]

The patch that did set the calls in state error may not be the
complete way to happyness. This happened _with_ the patch that sets
the calls in error when the connection is in error. But I get
"Connection timed out" anyway :-( Nope, I don't know how
to get this behaviour "on demand".

habarber:~$ /usr/openafs/bin/fs checkv
All volumeID/name mappings checked.

habarber:~$ /usr/openafs/bin/fs checks -c pdc.kth.se
All servers are running.

BUT

habarber:~$ ls /afs
ls: /afs: Connection timed out

habarber:~$ /usr/openafs/sbin/rxdebug localhost 7001

And later if I look at all connections to 130.237.232.194 I have many but
not ANY of them seem to work.

But my /afs expired 50 minutes ago. So what in rx is not giving
me a new fine connection/call?
