[courier-users] Help please! Strange glibc errors generated by courier-mta and maildrop 06x error

[Bearcat M. S. <li...@fe...>]

Folks,

I've been trying to get courier-mat working for a week now. I'd like some help 
or at least a direction.

I am running Sourcemage Linux (Gentoo like) and everything is compiled from 
source using 64-bit code.

I have an amd-64 3000 running on a asus a8n-sli deluxe board with 1 gig of 
memory.

Versions
Linux:  2.6.13
gcc: 3.4.4
glibc (all locals included): 2.3.5
courier: 0.51.0
courier-authlib: 0.57
maildrop: 1.81

Symptoms:
Mail is stuck in my queue. I get the same mail from days ago in my queue over 
and over while my queue fills up.  Deleting the files in /var/courier/msgs 
and /var/courier/msgq does not help. Doing a "courier flush" does not empty 
the queue either.  Doing a 'mailq' as root will tell me i have about 1000 
messages in the queue and looking at the log files i see things like 
"queuedelivering=400, inprogress=4".  The value for queuedelevering never 
equals the count by the mailq command.

A 'courier-flush' will sometimes reduce this number, but since the mail 
doesn't seem to be leaving the queue i get mostly older messages.

Doing a strace on 'courier flush' tells me that some /usr/lib64 files can not 
be found, but i'm not sure this is the cause. See 
http://www.feline-soul.net/courier_flush for the strace

I can send mail just fine.


Debugging:
Looking through /var/log/mail/current (i'm using metalog) i see the following 
three things frequently, but not always and these three messages never appear 
together:
 
1) Aug 28 10:07:41 [courierlocal] 
id=00000000000AFB39.0000000043108F73.000060EF,from=<qui...@qu...>,addr=<mar...@fe...>:

2)  Aug 28 11:00:11 [postfix/local] CA1FA8861A:

relay=local, delay=419430, status=deferred (temporary failure. Command 
output: /usr/bin/maildrop: Unable to create a dot-lock. )

3)Aug 30 00:11:54 [courierlocal] 
id=0000000000029B1C.000000004313BB32.00004E12,from=<>,addr=<be...@fe...>: 
maildrop: signal 0x06

#2 is rare, and #1 and #3 are quite frequent.

I have recompiled glibc, gcc, courier, courier-authlib many times. I am 
authenticating via plain.  

Can anyone give me a hand?  I'm not sure how i can fix this.  Please let me 
know if there is any more information i can provide or have left out.


Thanks in advance.  Please don't respond to me via direct email as i may not 
get it anyway.
