OPNSense Becomes Completely Unresponsive

[wilj81]

I'm experiencing issues where my internet is dropping sporadically. Sometimes there are weeks in between outages and other times the drops occur multiple times per day. I initially attributed this activity to the ISP.

However, during these outages, my opnsense router is completely unresponsive (I cannot access the web interface, it does not respond to ping, etc). While opnsense is unresponsive, I can access other devices on the local network (meaning my switching equipment seems fine). Now, I'm beginning to wonder if, instead of an ISP issue, opnsense is failing somehow and not routing any traffic.

I've looked through logs and cannot find anything definitive. I would greatly appreciate some help in trouble-shooting/resolving these issues.

Thank you!

Need much more information.  What do you systemlogs say?  What is OPNsense installed on?  Do you have watchdog errors (mostly related to bsd realtek drivers)?

Took forever to figure this out, but it ended up being bad memory. Replaced the RAM, now running rock solid. Just throwing this here in case someone else is running into similar symptoms.
