Hi folks!
It looks like Timo nailed down the NFS issues we've been seeing here in last night's CVS build.
Anyone running Dovecot in a high-usage environment should check this out.
Here are some relevant ChangeLog updates that seem to address the problem:
2006-05-02 11:11 Timo Sirainen timo.sirainen@movial.fi
* src/lib-storage/index/maildir/: maildir-save.c,
maildir-storage.h, maildir-sync.c, maildir-uidlist.c,
maildir-uidlist.h: Adding mail to index while saving it had a
race condition. Fixing it required a bit larger changes. Switched
uidlist/index locking order so that uidlist is now locked first.2006-05-02 11:04 Timo Sirainen timo.sirainen@movial.fi
* src/lib-index/: mail-index-private.h, mail-index-sync-update.c,
mail-index.c: mmap_disable: When syncing in-memory index from
transaction log, we didn't skip external transactions which were
already been in our in-memory mapping, causing "Append with UID
n, but next_uid = m" errors.The build is available here:
http://dovecot.org/nightly/dovecot-20060503.tar.gz
Thus far, I've seen no complaints of corrupted indexes or core dumps. This is absolutely fantastic.
As always... hats off to Timo. Great work!
