Collaboration Matters!

Got the same issues, but not with every IMAP user.

Only 1 user manages to crash the server when connecting.

I managed to get in touch with one of the developers at LS, and gave him all my dump and log files, with imap debugging on 'verbose'. Hope they an fix it soon. I gave the problem-user a new mail-file (after doing many compacts/fixups/updalls on the old one), transferred the emails manually (via Notes), and my server no longer crashes.

IMAP is used by one user on Domino 8.5/Linux (CentOS) and no matter!

Imap stability on Domino has been a constant thorn in our side...I was hopeful for 8.5. Mike Gagnon I hope you're reading this....

Stuart;

Thanks for posting this!!!

Might you be able to share the pmr/spr #'s, we're moving many accounts to domino using IMAP, and we're watching all things IMAP as closely as possible. Email to me at the above or post as a comment. Thx again, Dan

Stuart,

IMAP , while not really advanced in 10 years, is very simple, yet poorly executed by most admins.

Since others have said it works for them, one must presume there may be an issue, within the mail file itself, the ODS, the IMAP conversion task(which could be the culprit), some bad doc in the IMAP mail file.

As Theo said, have you tried to recreate a fresh brand new IMAP mail file and see if it crashes as well? Could it be the USER has botched up their mail template in their replication by upgrading them selves to a different version of the mail template which is not quite IMAPified (I'm American I can make up words).

My one client with IMAP running hasn't reported anything, but he is running on a Windows platform.

Await further info on this one.

@1 We are seeing the issue with one mail file (mine as it happens) but we only have a handful of users on this system. We've tried everything to resolve this - fixups/updalls/compacts/design changes/disabling&enabling IMAP etc, and the behavious remains.

It is a big mail file - over 1.5GB with hundreds of nested folders so I'd be very reluctant to start afresh and copy over the mails, but will do so if required.

@2 Glad to hear it!

@3 Me too - I wish more of the IMAP protocol was supported (IDLE) etc, but stability is the main requirement.

@4 The SPR is JCHS7NNM56

@5 Thanks Keith. All good points of course. But... This mailfile has been checked and checked again - including using all the tools available on the Domino server.

More importantly, it worked at Domino 8, 8.0.1, 8.0.2 and 8.5b2. The move to Domino 8.5.0 has resulted in the symptoms we've seen. In addition, multiple other customers have seen the same issue.

Hence my warning - I don't want other customers to upgrade and to hit this issue - this isn't just one mail file that can't be accessed, it is an immediate crash of the entire Domino server, and it will be repeated every time said user(s) connect to the server.

I don't like to make a big thing about code issues - Domino's a big product and any new release is likely to have a bug or two. However, in this case the impact is so significant that I thought it worthwhile raising here.

We had a problem with 8.5 and a specific mail file(it turned out to be mine!) which IBM analysed on their PMR (for those with access - it's PMR 83098,999,866) as a corupted MIME header when collecting email to an IMAP client (Thunderbird in this case). The effect on the server each time an IMAP synch was called by the mail client was immediate - it crashed and wrote NSD logs each time. I even stripped and rebuilt the 8.5 Notes server twice to see if it was a faulty DLL or similar. We've been using IMAP for a long time and this is the first time we've ever had this happen. I do remember an MS Exchange server crashing through a similarly malformed MIME object some years ago and it tok ages to find. At least in this case the NSD log pointed to the precise mail file that was causing it and I rebuilt it completely - and now the problem has gone away.
