Administer CPR immediately.  Or did you have another definition of 
"choking"?  :-)

For hardware, 512mb is like $140 these days and a U160 hdd isn't much 
more.  For software, you can try more maxservers if you're not maxing out 
your RAM already (don't count too much for hdd caching).  Also try rpc 
mode.  You can index your database really well, too, and don't forget to 
regularly expire your sessions.  You can optimize your apache (lots of docs 
on that).  There is also a lot to do for optimizing the OS (new kernel, 
disable "last accessed" on file systems, etc.), but focusing more on IC is 
probably a better use of your time.  Good luck,
