PAN-OS 8.1.0 SMB Issues

L5 Sessionator

Hello all,

 

Please be advised, there is a current issue with PAN-OS 8.1 which seems to break anything SMB related, e.g. mapped network drives. Sessions have an end reason of "resources-unavailable" and go into state "Discard" in the session table.

 

Upon speaking with a TAC engineer, this is a known issue and they are working towards a fix.

 

Edit: This is now resolved in PAN-OS 8.1.1 under BugID:

 

PAN-94445
Fixed an issue where Server Message Block (SMB) sessions were in a discard state with the session end reason resources-unavailable

 

Thanks,

Luke.

TAC suggest to create an application override policy as workaround or downgrade to 8.0.X PANOS version.

Did you try the Application Override or did you downgrade?

Applicaton Override does the trick.

I didn't have time to mess around on Sunday when this was discovered, so we downgraded.  Thankfully that went smoothly.
