Hi Timo et all. At last I found with unix socket wouldn't connect and it works now. However after auth, imap crashes with signal 6. This happens on 1 machine, the other (unixware too) work fine. The stack trace doesn't make much sense here it is anway...
Core image of imap (process p1) created CORE FILE [makedev in cmd-status.c@sys/mkdev.h] SIGNALED 8 (fpe code[FPE_INTDIV] address[0x804e38b]) in p1 76: return __makedev(ver, maj, min); debug> Stack Trace for p1, Program imap *[0] makedev(maj=16, min=1, presumed: 0x8094258) [cmd-status.c@sys/mkdev.h@76] [1] cmd_store(cmd=0x0, presumed: 0x1, 0x80947a0) [cmd-store.c@139] [2] _cmd_select_full(cmd=0x8072498, readonly=false) [cmd-select.c@84] [3] cmd_store(cmd=0x10, presumed: 0x807d184, 0x8047cac) [cmd-store.c@74] [4] minor(dev=134511756, presumed: 0x8055266, 0x8047cac) [cmd-subscribe.c@sys/mkdev.h@112] [5] imap_search_args_build(pool=0x8047cac, box=0x8047cb4, args=0x8047ca0, error_r=0x804ebc1) [imap-search.c@416] [6] imap_search_get_uidset_arg(pool=0x1, box=0x8047cac, uidset="\215}\004\b\235}\004\b\245}\004\b\020\220\b\b\313}\004\b\335}\004\b\357}\004\b", arg_r=0x0, error_r=0x0, 0x1) [imap-search.c@447] [7] cmd_append_cancel(ctx=0x8047cb4, nonsync=true, presumed: 0) [cmd-append.c@158] [8] ?() [0] debug>
The log says Trying to allocate 0 bytes and imap gets killed.
Does it ring any bells?

Well, that really doesn't make any sense. It just can't happen, so those function names were looked up wrong.
The log says Trying to allocate 0 bytes and imap gets killed.
Hmm. There are quite a many ways for the code to get here. I tried looking if I could find some way to cause this myself, but didn't succeed. So pretty difficult to get fixed without a correct backtrace..
Hi Timo,
I'm glad to tell that dovecot is in prod on Unixware since yesterday.
See below...
Many thanks for your help. On Sun, 5 Feb 2006, Timo Sirainen wrote:

You fixed the earlier problems when connected on my machine, then I put net_set_nonblock() AFTER the connect in net_connect_unix() to avoid the EINPROGRESS race condition I talked about in my previous mail.

This one took me ages to find what happened. I was first supprised that it only occured on one machine that hadn't the latest unixware patch.
Alas applying this patch crashed the machine but that's another storry.
Anyway it turns out that the imap crash was caused by a bad ns.so library (yes this machine use NIS+) and each time the "standard" userdb was checked imap crashed.
I hav'nt yet analyzed why (other calls to getpwnam, getspnam work corectly), but I made it work by commenting userdb passwd and enabling userdb passwd-file with /etc/passwd as passwd file.
Now I wonder what kind of magic you do when checking passwd... :)
In any case, it works for me now!
