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:


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