Could not setup Mach... on Mac OS X 10.5.7

[addihetja]

I'm running Zimbra 5.0.18 GA on Mac OS X 10.5.7. It had been running fine for a few weeks but I had to move the server to another network (identically set up) and now I get the following every two minutes in the system log and sometimes in between:

Jul 31 00:12:00 host com.apple.launchd[1] (0x10d2b0.sshd[11632]): Could not setup Mach task special port 9: (os/kern) no access

I have narrowed it down the the zimbra crontab; if I disable the crontab file it will not produce the error. The only thing I can find in the crontab that matches the time is this line:

# Status logging
#
*/2 * * * * /opt/zimbra/libexec/zmstatuslog

I've tried restarting the machine, manually killing all zimbra processes and restarting ZCS without any luck. Is there something that I'm overlooking?
