Hello, we're having the same problem with Cyrus 2.5.11 on XStreamOS/illumos Any idea how to fix this? Same problem both on 32 bit large files build, and 64 bit. Looks like the Debian issue has no solution. Can't believe this has never been addressed.

We have a problem that squatter segfaults on some quite big mailboxes. I had to add -i (--incremental) to at least index new mails. But users cannot search in old mails (before migration). I used strace to find out if it is some particular mail, but it parsed everything fine, and failed when dealing with some of the many temporary files squatXXXX. The problematic mailboxes have just inbox10 GB (and15 GB with all subfolders) and20000 emails in inbox. Has anyone else hit similar problem and solved it somehow? I'm not sure about fixes, but there are some reports of similar problems. Have a look at the thread with the subject "Cyrus 2.5.10 IMAP search" from the beginning of June this year. Apparently the format of the squatter database changed between 2.4 and 2.5, and some people (at least) have seen a 10x increase in the size of the squatter database for the same mailbox. For systems that only allow 2GB mmap, this can be a problem. I'm not sure if this increase in size is a bug or a feature. Mark Hello Mark, Thanks for the hint about old discussion. Unfortunately, there was no solution to this issue mentioned. I found out that this was already reported to debian, I wonder whetrher the maintainer forwarded the bug report upstream. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871921 This is on 64-bit Linux, so mmap should not be limited to 2 GB. And I also have noticed the extreme increase in squat file sizes. -- Best Regards Vladislav Kurz ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
