If two users request the same .exe within about 1/10th of a second, they collide; one completes, the other hangs until timeout some minutes later. The only problem is, while that one is hung, further requests for the same page also hang. The stack gets large rather quickly. First hack was a tool to kill the rogue processes. Latest, uglier hack is... Are you ready to shudder? For five power users, I took three of the most-requested (and most-crashing) pages, and made per-user copies of them. So one app named "SeekMT.exe" now has copies named "SeekMTLBAR.exe" and "SeekMTSROL.exe", etc, in the same folder, to which each of those power users gets referred instead. Kill me quickly.

Post #106,461 by tseliot 6/18/03 4:31:03 PM Reply	Apparently not. The biggest issue seems to be when the apps call out to a third-party (irreplaceable) DLL (which supplies an API to their product). I've known this to be the source of much of the conflict--and have been slowly working on working around it. It just got to be too much today. :) Many fears are born of stupidity and ignorance - Which you should be feeding with rumour and generalisation. BOfH, 2002 "Episode" 10
Post #106,465 by admin 6/18/03 4:58:55 PM Reply	Ah.... Wrap the DLL with a call with mutexes, maybe... kinda like a synchronized version of an unsynchronized object in Java. :-) Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."
