Domino 8.5.2 HF1 – the fix for the unread synch server crash


I would like to bring your attention to the SPR# RMAA88UAGF – server crashes when clients synchronize unread marks on Domino 8.5.2 servers.

I ran into this last week when we had some unexplainable server crashes for apparently no good reason – one of them happened when I was showing a help desk tech how to synchronize unread marks between replicas from the client. I investigated and the crash report that Domino gave me pointed me right to this error – now fixed in FP1. It is a regression bug and is not fixed in either of the previous hot fixes for the Domino 8.5.2 code stream. I had servers with both the SMTP patch and the interim fix (IF) as well – they all crashed at one time or another. I installed HF 1 on all servers and now they are safe from this issue – I tested it on all of them just to be on the safe side.

If you don’t have HF 1 installed yet – do it soon, this one can happen at anytime during¬† the day and there is no warning whatsoever. only a big “boom” when the server disappears from the face of the (electronic) earth. Incidentally, there are allot of other problems that are fixed in that HF as well – I suggest you look into it right away and consider upgrading all your Domino 8.5.2 servers soon.
