MailScanner debug mode fails! (FreeBSD 6)

[Remy de Ruysscher]

Hi all,

I've been experiencing some nasty errors with MailScanner in the last
week, currently my mailserver is down (1800+ mails in the queue) and I
can't get it to work!

What I've done so far:
Rebuilding world/kernel and upwards recursively portupgrade all perl ports.

[root at unix-asp ~]# MailScanner
In Debugging mode, not forking...
Fatal error 'Cannot allocate red zone for initial thread' at line 364 in
file /usr/src/lib/libthr/thre
               ad/thr_init.c (errno = 12)
