Watchdog question

[macarlo]

I'm using Plesk 8.1.1 (recently updated) and a problem since 8.1 is not resolved. All runs fine but I simply cannot make one change in Plesk CP, as setup a cert, for example, because Apache fails, the golden square icon in Watchdog monitoring httpd is replaced by a round red one and Apache goes down and it is no more restarted by Watchdog. Recently due this problem I was forced to restart httpd manually around 200 times in only one day!Q@!! After this period Watchdog returned at golden square icon by itself and send me this message: "The Web Server (Apache) service on host vps.macarlohost.net has been released from monitoring on Apr 6, 2007 07:14 PM."

For various times I experienced this troubleshoting. I'm running Fedora Core 5 on a VPS by Virtuozzo.

If any expert there know the procedure to solve this problem I thanks a lot in advance!!
