[linux-cifs-client] mount error causes runaway network traffic with multiple users

[Andy Loukes]

Linux 2.4.24 cifs-client 0.9.9a

I am trying to mount two shares with different users from a win 2k3
server. I have only just started using cifs-client (to support the 2k3
server). I've tried this with MultiuserMount set to 1. I can mount the
share from either user separately, or multpile shares with one user. But
if I already have a mount and then try and mount as another user it fails
with this error: mount error 22 = Invalid argument

and dmesg shows:
 CIFS VFS: Send error in SessSetup = -13
 CIFS VFS: cifs_mount failed w/return code = -13

and then the network traffic goes nuts until it fills the ip_conntrack 
table with entries like this (10.0.0.92 is the client 10.0.0.56 is the 
server)

tcp      6 8 CLOSE src=10.0.0.92 dst=10.0.0.56 sport=53669 dport=139 
src=10.0.0.56 dst=10.0.0.92 sport=139 dport=53669 [ASSURED] use=1

it just seems to continue at about 15 packets a second!

Is this a known problem, what other information can I supply to try and 
debug it?

Regards,
