I've seen something similar. I have a Mac Perl CGI that searches a 
database, and a malformed search was effectivly requesting the return 
of the entire database. I already knew that this wouldn't work once 
the length of the return information exceded the maximum return from 
an Apple Event (32Kb? 64Kb?) since I started getting 'Document 
contains no data', but is seemed that exceeding this by lots caused 
something in Mac Perl or the glue to get very confused. Symptom was 
as you describe - the CGI would not work and would not quit.

The simple solution was to screen out the dud requests, but there is 
probably something that needs fixing somewhere to stop the crashing.

Jon.
