T3400 4gb RAM FX1700 XP 64bit. SW2008 SP05 My company is having stability problems following our recent upgrades. New machines with the above specs. One of the biggest complaints is with Mating and deleting mates out of large assemblies. Solidworks will just crash with no error warning. It shows less than 2gb of ram taken up on this specific assembly when it is open and the processor never gets more than 30%. The users seem to complain that most crashes happen when PDM and Solidworks are interacting. All Engineers are on gigabit ethernet. Anyone have any pointers on what we can try?
