The old V19.5 GA Thread: Sophos Firewall: v19.5 GA: Feedback and experiences
Thanks for providing support access to the setup.
We are able to narrow down the problem and tracking it under NC-115369 for further RCA and fix.
There was remote network scan for /16 network getting performed over VPN, which was creating huge incomplete neighbour lookup entries. As a side effect it was causing routing demon restart.
After stopping that scan OSPF has been stable now.
Moved from 19.0 MR1 to 19.5 MR1 and have extreme problems with OSPF.
We had OSPF enabled before the update and used it without problems but now after it seems crashing every 3-10 minutes.
This behaviour occurs on 50% of our XGS116 appliances, on the other 50% it works fine.
Hi Sebastien HENRY can you share the case ID that was created with Bhavik. We can check if the logs are collected while creating the case , If so we may be able find more info on what happened for 19.5.1 .-Shrikant
thank you for this information which may help other people.
It's unfortunate that the French Sophos telephone support did not tell me.
I would have saved a lot of time...
There can be (unrelated to the firmware version) issues with the services, providing the clientless users.
Most likely, if this is the case, it is a one time issue: 
Restarting the Authentication daemon fixes this and it should not come up again.

Hello Bhavik24,
Sorry, but everything was erased due to firmware rollback.
I had opened a case with SOPHOS, but it was closed following my switch to 19.0.2
FYI, when I booted to firmware 19.5.1, absolutely no clientless users appeared in the list of active users (under current activities -> live users).
After returning to 19.0.1, everything appears again.
After migration to 19.0.2, everything also appears correctly.
Hello Sebastien HENRY ,
Have you notice any specific error during clientless user recreation?
If possible, then please PM me appliance access detail so I can debug further.
Thanks
Hello,
very bad experience for me.
I upgraded from 19.0.1 to 19.5.1
After the update, user authentication works poorly, and they have to restart their PC.
I lost all "ClientLess User" access
Even when recreating by hand, the firewall does not allow flows to pass.
I had to revert to 19.0.1, then update to 19.0.2.
And there, everything works perfectly.
I can only advise against version 19.5.1 :(
