>Description:
Running 122 virtual domains, exec cgi stops working. Since exec cmd 
still works, I don't think this is a problem with OS configuration, 
but I may be wrong. I tried increasing /proc/sys/kernel/file-max 
and /proc/sys/vm/freepages and that didn't change the problem, but 
I commented out a few virtual domains and the problem went away. 

I need to know what resources I'm running out of. The message in the 
error log is "couldn't spawn child process". But why would #exec cmd 
work and not #exec cgi? Looks buggish from this end. 

TIA,
