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.

Subject: [mapserver-users] mapserver fastcgi warnings when msQueryByPoint()
Search returns no results
I am not sure if this is a problem or not but I was wondering if anyone else
has experienced fastcgi warnings with every msQueryByPoint that returns no
results ? 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:
