1. You may be experiencing a memory leak, which may or may not be caused by the VMware product in question. For more information on memory leaks, see http://en.wikipedia.org/wiki/Memory_leak. Restarting the computer where the product was installed can resolve the isse, but this may not be a permanent resolution.
   
   
2. It is possible that corruption occurred after the product was installed or during the installation. Uninstalling and reinstalling the product may be necessary. If you do not have access to the original download, you can download the product installer from the VMware Download Center.
   
   
3. If the issue persists, you may be encountering a hardware issue. Run diagnostics on your hardware, and ensure this is not the source of your issue. There are many utilities that can perform this operation, and some manufacturers have access to utilities that help you to determine if there is a hardware problem.
   
   
4. If your hardware diagnostics pass, you may be experiencing an issue that requires further troubleshooting. File a Support Request with VMware Support. For more information, see Filing a Support Request in My VMware (2006985).
