Pen Testing OPNsense Crash

[opensourcefan]

I've been learning Pen Testing and have been using Kali Linux. The other day I was attacking my alternate WIFI network sending multiple deauths etc when somehow I ended up crashing my OPNsense instance. Reboot fixed it, but couldn't see anything obvious in the logs unless I'm looking in the wrong spot.

Is it possible there's a correlation between my testing and the crash? If so where should I look to see what happened. I'm installed on baremetal with 8Gb of RAM and a decent CPU.
