Sandbox Permission Issues

[dankessler]

When attempting to troubleshoot a support ticket for Ivy dealing with the FirstLevel script, we came across some weird path building errors that appear to be related to permissions in sand box directories.

My solution was to go into the sandbox and manually delete all of Ivy's folders, at which point things ran cleanly again for a while before ultimately falling down with permission issues again. Disabling the sandbox fixed the problem.

I can take a look.

Not sure if either of these is the case but there are sometimes problems with deleting sandbox folders for some reasons, and so I’ve seen problems happen when the sandbox disk space is exhausted. Also, sometimes I’ve seen problems when things end up in a weird situation due to crashes/etc with the user being in the sandbox folder as their working directory, but then the sandbox folder gets blown away and Matlab throws errors because of the path problems.

Yes, I recall her also reporting that she consistently saw error messages
near the end of execution of many of her scripts with reporting that
sandbox could not be removed/deleted, so sounds like you're on the right
track :)
