    Default Stops sending

    I just installed 8.0.3 on U12.04 yesterday. 3 times now it has just stopped sending mail a timeout message appears.
    I restart the mta, zmmtactl, this seems to allow it work again. The only thing I see in the log is
    Apr 3 12:12:22 zmail5 zmmailboxdmgr[31297]: no manager process is running
    Apr 4 08:27:52 zmail5 postfix/smtpd[23089]: fatal: watchdog timeout
    Apr 4 08:38:20 zmail5 postfix/smtpd[28997]: fatal: watchdog timeout
    Apr 4 08:39:59 zmail5 postfix/smtpd[29550]: fatal: watchdog timeout


    8:27 is when the mail stops sending. I am not sure where else to look.
    I also found this
