QB Issue Resolution:

Something is wrong – memory is getting corrupted. Is this error coming from the QuickBooks user application or the QuickBooks server application?

You probably should try rebuilding your file. To do this, quit all copies of QuickBooks. Then launch the QuickBooks client application on the machine that was running the server. Open your company file in single user mode. Then run File->Utilities->Rebuild.
