Using the TOP caommand I can see that it is using 98% CPU and not accepting and any requests from inside our network or out. The only way to fix it is to SIGHUP the httpd daemon. That seems to work until the next time. We do have about 50 virtual servers running on our system, but we upped the minservers and maxservers parameters in the httpd configuration files to try and compensate. Any suggestions would be appreciated. Thanks, Fred Brechbiel Sys Admin Southern Maryland Internet http://www.chesapeake.net
