Sonicwall Netextender VPN Strangeness – MacOS

If you get the following strange message when attempting to connect to the VPN using Sonicwall Netextender on MacOS:

FATAL: An immediately fatal error of some kind occurred, such as an essential system call failing, or running out of virtual memory. (1)

This little problem took me forever to find, as I don’t generally expect file permissions to randomly change. I’m still perplexed as to what caused the change, but I did run CCleaner the other night, right before this happened. Hmm…
