Dear gentleman,
I am running qmail, and it's dying at least 2 times a single day.
I decided to run ktrace for it, here is what i got:

Here is my /var/qmail/rc:
#!/bin/sh
# Using splogger to send the log through syslog.
# Using qmail-local to deliver messages to ~/Mailbox by default.
# This is the default (use after execv env) qmail-start ./.Mailbox
splogger qmai
l
exec env - PATH="/var/qmail/bin:$PATH" \
qmail-start ./.Mailbox /usr/local/bin/multilog t s100000 n10
/var/log/qmail &
#qmail-start ./.Mailbox sh -c 'accustamp | cyclog /var/log/qmail'
# end of /var/qmail/rc
Can you please suggest me something to fix this.
I don't really know what to do.
Thanks a lot for your time and cooperation.
