Visualizer creates large dump files that aren't deleted and the user is not informed

[tkuchida]

Steps to reproduce

Dump (.dmp) files are created in C:\Users\%USER_NAME%\AppData\Local\JxBrowser, presumably when the Visualizer crashes. Currently, the Visualizer crashes when I open and close a few models in succession without restarting OpenSim in between, or when working with models like Rajagopal2015.

Expected result

OpenSim does not continue consuming hard drive space without informing the user. If .dmp files are created, OpenSim should either delete them automatically or inform the user when they take up more than a few GB of space.

Actual result

I ran out of space on my hard drive. My JxBrowser directory contained 54 .dmp files which consumed 59.4 GB of space.

Environment and GUI version

Windows

I realized this is still a problem with opensim. My SSD just got full and my pc doesn't have many apps or documents so I thought it was weird. After a while I realized it was the JxBrowser folder that had 150GB. Is it safe to delete those .dmp files?

@andrersvieira Yes, the .dmp files can be safely deleted 🗑️

@tkuchida thank you! is there a way to prevent these files from being written in the future?

Not that I know of (though presumably the issue will be addressed eventually). If you want these files to be deleted automatically, you could write a .bat file to navigate to this directory and del *.dmp when your computer boots, for example.
