Keeps crashing and other

[macgvr]

I had to pull the Opnsense firewall because it kept crashing every couple of days. When it crashed, I couldn't connect to the web interface or ping the lan card. When I checked the connected monitor, the screen was just full of jibberish. I didn't have time to troubleshoot at that point because I was going to be out of the office for 4 days. When I got back I started checking things out. Checked the logs but couldn't find anything, may have lost the pertinent log info because of the delay in looking at it. Did full diagnostics on the hardware but found nothing wrong. Ran it for several days off a live Linux Mint cd without any failure. I decided to set it up on a secondary network I have but it hasn't run long enough to reproduce the failure, apparently. Wondering if anyone else has experienced this or how to find out what is happening. I also updated to the latest version today, 16.1.17 - I think, so maybe this issue won't return.??
