Hello *,

Not sure if this is to much OT for this list:


Around 10 000 + messages in dmesg / syslog like this:

CIFS VFS: Send error in SessSetup = -126
CIFS VFS: Send error in SessSetup = -126
CIFS VFS: Send error in SessSetup = -126

the concerned site does cifs mounts for individual user homes against netapp servers
There is only one server showing those multiple messages.

How may one trace best what is going on ?
