We are running AutoCAD 2005 and Pro Engineer Wildfire on our Windows XP Pro machines. All data files are stored on a SNAP Server 1100 across our network. On 3 separate occasions 3 separate users were working as usually and somehow 1,000's of savXXXX.tmp files were created in their working directory. The XXXX were HEX characters counting upward. This caused the server to lock up and force a reboot. These servers are vital for our business and we can't have this keep happening. I've deleted all the tmp files that were created but not sure how to stop this from happening again. Any help is appreciated.
