This scenario comes up on a pretty regular basis and I don't think 
that anyone has ever offered a definitive explanation for what is 
going on. I've never run cgi on ASIP server, but have encountered 
exactly the same kind of behavior using NetPresenz and Apple Web 
Sharing and have seen posts outlining the same kind of problem from 
people using other Mac servers.

I got too frustrated to pursue this and just deal with Apache or 
Netscape servers now, but my theories are that:

1. The Event Manager is getting winded and/or
2. Open Transport is not up to the task and/or
3. There is a memory leak somewhere and/or
4. MacPerl's cgi scheme is not robust enough to pull things off reliably.

My only suggestion is to go into the individual cgi applets and bump 
the default memory allocation from 200k (or whatever it's set at) to 
a larger value. It might not hurt to also reinstall MacPerl and raise 
it's memory to whatever the maximum practical amount is for your 
server (after allowing for the possibility that all of your applets 
could be open at once).

Since this behavior is unpredictable, it's hard to actually pin the 
cause down, but you might (or might not) get somewhere by running AE 
Capture and OTSessionWatcher to see if you can determine what 
triggers it. Good luck and let me know if you ever figure this out.
