can you tell what is the mod_fcgid version on each server? If the 
version is the same, you may be facing the same bug on each server, but 
for some reason it's not triggered on Debian Sarge.

Anyway, if it's a bug and we have to relase an update, you'll have to 
compile from source and not from packages...

very good to know, except if the module on etch is an old version. Have 
you set the same fcgid directives in your apache configuration?

AFAIK Etch is newer than Sarge (I'm *really* not a Debian expert, made 
my own OS), so the fcgid module is probably newer as well. Last version 
is 2.2 and some hardcoded variables related to the scoring (the 
mechanism which determines if a new fastcgi application has to be 
spawned) have been changed.

BTW, have you got anything related to mod_fcgid in your error log? You 
have to log some info or debug level errors in your apache config. Maybe 
you will find some interesting stuff.
