When your GUI is crashing are you connecting via the browser or local install?
I can probably help you with the local install piece to prevent it from stalling out.
- Locate the shortcut on your desktop for the CommCell GUI
- Right click and bring up the properties window and find the target text box
- Add the following text at the beginning of Target: -Xms128m -Xmx512m
-jar cv.jar commserver.commvault.com 8401
Change this to
-Xms128m -Xmx512m -jar cv.jar commserver.commvault.com 8401
This will set the initial heap size to 128 MB and maximum heap size to 512 MB.
Again, this will only help you locally and not via the HTTP connection but it should improve your performance.
Let me know if this helps.
