We have had major problems on 3 Debian 3.1 servers running Plesk 7.5.4 The qmail-send service keeps stopping at random times throughout the day. You can still SMTP connect TO the server and deliver inbound, but local and remote queues for outbound delivery fail until the qmail-send service is restarted. This can, of course, be done through control panel. Since Sunday night our monitoring has logged over 50 times where this service has stopped. We have disabled watchdog per suggestion, but that has not stopped the problem. This is costing us in terms of support and customers since the service must be manually restarted each time. Any suggestions would help. One thinge we did do was change the nowait to nowait.200 in innet config, but that only seems to have helped a little. Also, queue size has been anything from 81 to 3000+ messages when service stops/fails Thanks!
