Not a fcgi expert, but looking at the code any error calls writeError() in mapserv.c which ends with exit(0). So as written the behavior you're seeing is expected. I don't believe there is much overhead with restarting though.

Everything works as expected when querying a point that returns a result or simply panning or zooming the map. However, when a user clicks on the map and the query returns no results the fastcgi terminates the pid and creates a new one. Is this normal behavior ? I am very much a novice with fastcgi but it seems like this will slow things down and is counter intuitive to using fastcgi. The user experience is not affected but if we could make things faster that would always be good. We are using the following setup: Ubuntu 64bit Server - 10.10 Mapserver 6.0.1 Apache/2.2.16 mod-fastcgi 2.4.6-1 Below I have included a except of the mapserver MS_ERRORFILE and the apache2 error log: MS_ERRORFILE [Thu Jul 5 21:42:22 2012].92065 CGI Request 2 on process 27946 [Thu Jul 5 21:42:22 2012].231782 msQueryByPoint(): Search returned no results.
