Subject: the $5 bet - crash a server with unlocked application scope
READs
The subject pretty much says it all, but I'd like to see someone crash a
server or produce a pcode exception error or (getting easy here) produce one
of those "donteverusethisvariablenameinyourcfmlcode123456789" errors by
using concurrent unlocked application scoped variable reads.
I've already built a frameset with 50 frames, each frame page looping over
the output of an application variable 100,000 times. Now out of those 5
million read hits to my application variable that occur within the space of
maybe 10 seconds, NONE produce any error whatsoever, no matter how many
times I try. Of course, doing 5 million WRITE hits will produce errors
pretty quickly, and eventually destroy my server. Anybody have Silk or Load
Runner?
I'm not interested in session variable locking issues, nor with cfquery's
cachedwithin attribute. I only want to see application variable reads
causing detrimental effects to a CF server.
$5 to be delivered at the next major CF conference, should I be able to
reproduce the error on my machine (single proc p3-650, 256 mb ram, CF 5 Beta
3, PWS, NT 4 Workstation SP6). The cash only goes to the first person...
Good luck - I don't think it's possible!
