texte = Yes I've seen this too. I've seen it on RedHat 6.2 and 7.1 running WC 4.5.1 and I've seen it on RedHat Ent 3 running DNA 6. *EVERY* time it has happen I have tracked it down to one of the following reasons: 1. Sendmail has a very large message stuck in it's queue. When the message attempts delivery and fails to send it overloads the server for a split second and causes WebCatEngine to quit. 2. An unexpected run time error due to my incorrect coding. 3. A bad input variable from a form field that I forgot to wrap inside [url][/url]. I feel that the WebCatEngine should be a little more resilient. Instead of quitting it should throttle back or time out for a fraction of a second rather than totally give up, then a moment later it could recover.
