Internal Error on SMs running 20.1 and 20.2

With SMs running 20.1 or 20.2, we have been noticing a large amount that only show “Internal Error” when you pull up the SM GUI. updating the firmware seems to be fixing them (they aren’t losing access), but is anyone else seeing this? is this something fixed in a specific firmware version?


I have a ticket open on this now. Looks like there’s an issue when using opt66 file where it’s filling up the memory and filesystem, as it reimports the config every dhcp renew. This was working without issue previous to 20.1
