Signalled to death by 13

[Nikola Milutinovic]

Hi all.

Cyrus IMAP 2.2.10
Cyrus SASL 2.1.20
Tru64 UNIX 4.0D

I'm seeing a lot of these in my logs:

Dec 28 08:02:14 Uprava master[25111]: about to exec 
/usr/opt/Cyrus-IMAP4-2.2.10/sbin/imapd

Dec 28 08:02:21 Uprava master[492]: process 25111 exited, signaled to 
death by 13
Dec 28 08:02:21 Uprava master[492]: service imap pid 25111 in BUSY 
state: terminated abnormally

Could anyone comment on two things, the initial NTLM failure (minor 
importance) and the "signalled to death by 13"?

Signal 13 on Tru64 is SIGPIPE, the explanation is "write on a pipe with 
no one to read it". Why would IMAPD be writing on a pipe anywhere? Does 
it have to do anything with NTLM?

I must notice that my account is not causing this and I am using Mozilla 
1.7.3, IMAP+TLS+CRAM-MD5. All other users are using Outlook Express with 
"Secure Password Authentication", which defaults to NTLM for a machine 
not in Active Directory.

As an experiment, I've removed SPA on several machines, so I'll see if 
it makes any difference.

Nix.
