I'm seeing both of these dumps on multiple users now with 1.2.9, so I
went ahead and did backtraces for them both.
maildir_uidlist_records_array_delete panic: http://pastebin.com/f20614d8
ns_get_listed_prefix panic: http://pastebin.com/f1420194c

Just wanted to update you that I just upgraded all of our servers to
1.2.9 and I'm still seeing the array_delete panic:
Dec 21 12:10:16 gehenna11.rutgers.edu dovecot: IMAP(user1): Panic:

I also started receiving a good deal of these, but only from one user
so far:

Let me know if you need full backtraces from the core dump.

I applied those patches to my 1.2.8 installation before 1.2.9 was
released and that immediately fixed the expunge crash, but the
array_delete bug is still there.
Do you also see the "duplicate file entry" before the crash?
Yes, the duplicate file entry is always reported immediately before
the crash, just as Ralf reported too. You can see it in this example
pastebin I took from one of our users:
http://pastebin.com/f29c55de5
maildir:~/Maildir:INDEX=/rci/nqu%h/dovecot:CONTROL=/rci/nqu%h/dovecot
Are the index/control files on NFS? Are there multiple different
servers
accessing mail data?
Correct. All index, control files, amd mail storage are located on
NFS and there are multiple load balanced servers accessing the NFS
data. We're currently running with:
mmap_disable = yes
dotlock_use_excl = yes
fsync_disable = no
mail_nfs_storage = yes
mail_nfs_index = yes
