Web server stopped serving pages this morning.  Not sure what went wrong but I was able to login to it okay and Apache still showed running.of life, will be stable.

     An update, it is not a problem with the web server but a problem with WordPress plugins.  For some reason the particular collection I use which got along fine until an update to Comet Cache now hangs.

     As a temporary fix I am going to remove Comet Cache from our main site.  This will make it slightly slower until an update to fix becomes available.
