[Dovecot] (mail_index_sync_update_index): assertion failed
Anyone run into this one? I'm using test53...
Dec 3 13:08:17 aurora dovecot: IMAP(doug): file mail-index-sync-update.c: line 1160 (mail_index_sync_update_index): assertion failed: (map->records_count == map->hdr.messages_count) Dec 3 13:08:17 aurora dovecot: child 65942 (imap) killed with signal 6
It doesn't seem to correlate with any particular action. The only change I make to the compilation is to comment out #define HAVE_FREEBSD_SENDFILE
Thanks,
Doug
Anyone have a hint as to how I might successfully debug this problem?

Hi Doug,
I think this might be because there is a space between /home and /doug/Maildir/dovecot.index It would then see the /doug/Maildir/dovecot.index as a second argument.

Andrew,
Thanks for taking a shot at diagnosing this. That space is actually an artifact of me pasting log entries into the email. It doesn't exist in the config file or anywhere else.

Sorry Doug, just tried to investigate a bit (I am not the best programmer in the world). Msync should be called as follows:
int msync(void *addr, size_t len, int flags);
It looks to me in your case the parameter 2 is supposed to parameter 1 and I don't know what the heck got shoved in parameter 1. Maybe parameter 1 was supposed to be parameter 2 without the 0x??

The ktrace output has "msync(0x130960000,0x1aff4,0)." Ktrace doesn't have access to the information from the original source, so it's not able to resolve the first argument to the void pointer. What ktrace shows looks right for the first argument, though -- a full 32-bit address.
The second looks like it's within a valid range as well, as is the third.
The problem I'm seeing is that the second argument is not a multiple of the machine's pagesize. The man page says that such an issue will result in the error as seen.

I don't see any man page saying that length argument must be a multiple of page size and it hasn't been a problem with any other system I've previously used. What CPU is this with?
Yes, I need to learn to read. That's the addr argument in my man page, of course.
Sorry,
Doug
