If you are not doing cflocks *everywhere* you need to on CF5 then going to a faster machine will be more unstable than the same code on a slow machine. I haven't seen hyperthreading cause issues with CF before, for whatever that's worth. Mark

Since the move we have experienced cfserver.exe unexpectedly terminating. The latest being today. Based upon event id 4097 i went to www.eventid.net and found that is a memory access violation occured. Could this be related to the hyperthreading? or to cflocks and memory?? or both?? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Logware (www.logware.us): a new and convenient web-based time tracking application.
