Hi,

I know this isn't 'strictly' FreeBSD related, but considering this problem
doesn't seem to surface on other more 'penguin' like platforms, maybe someone
here can help?

We have Sendmail 8.9.1 and Cucipop 1.31 installed from the ports collection on
a 2.2.7 system. Everything works fine, except for 1 user...

They receive a lot of mail via POP3 (typically lots of Mb's). If they're
online receiving mail (via Cucipop) and mail.local runs to deliver mail to
their spool file, the system seems to hit a deadlock...

The mail doesn't get delivered (The mail.local process gets caught in
"LOCKF"), and Cucipop never quits properly - and is left hanging around for
ever in "LOCKF" state.

If you kill all the Cucipop's (we've had over 50 from when the user kept
logging in over the weekend to pickup their mail), then the mail.local(s) will
complete OK and deliver the mail...

Sounds like some kind of Deadlock... Anyone got any suggestions?

-Kp
