Description

It has been reported that there are incidences where VM (virtual machines) running Wonderware software experiences a significant loss of memory causing the VM to eventually lockup.  Rebooting the VM solves the problem temporarily, but the problem comes back within a short period of time.  Normal troubleshooting does not reveal any obvious memory leaks caused by running processes.
