I'm administer a VPS and I'm having major problems with apache going down all the time. I see a bunch of entries like this in the httpd error log file: [Sat Sep 01 11:56:22 2007] [notice] caught SIGTERM, shutting down Sometimes 20 or more times a day. I want to find out what process is sending the SIGTERM signal to apache. How do I do that?
Have you checked your cron jobs if they cause this? Or do you use a service like monit that shuts down Apache (due to high CPU load or memory usage)?
