UPDATE: I changed the Performance mode to AC-BFNA and now the interfaces start in 30 seconds. I used the GUI re-install now and it has fully restored everything back to normal now. Thanks again for your assistance.
Ah…your Snort process was probably running out of memory and/or using swap and getting super slow. Any Performance Mode other than AC-BFNA or AC-BFNA-NQ is a problem it seems. Lots of folks have reported issues when changing it to something else. Most of the other settings will eat memory like crazy, especially with lots of enabled rules.
