I have had my C7 for close to a year. I have discovered that when new code comes out, that i should not install it as it will consistently cause my C7 to stop responding to anything and stop processing automations. I have to pull the power to reboot it. I have opened ticket after ticket and i always end up getting "we dont see anything in the logs so are sending to engineering" and then never see anything else.
I had it running again where i didn't have to reboot it every day, and the latest code came out. I figured it was stable, and installed. Now it will stay active and responsive for an hour or less and then no longer respond to anything.
I have done a soft reset, factory reset, changed to previous versions of code, restored from backup and done everything i have seen in the help community, but to no avail.
This runs my security and safety lights at night and my pool alarm (windows and doors), as well as thermostats, lights inside and outside the house, so it has become a very large problem and a security concern.
I have it hardwired to ethernet switch. I have changed switches, ports, and cables. I am a systems architect for Cisco, so pretty clean network running including QoS to prioiritize network traffic to and from the C7.
Light stays green, have link access to switch, but nothing functions or responds, so no automation works (like turning on lights at night or activating motion sensors). The logs do not show any errors or issues, it just stops normal logging and picks up where i unplugged and replugged the power.
Is there anyone here or any engineering folks at hubitat who can help? I am ready to go back to home assistant because it stays up.
Thanks in advance for any help!
EDIT: JasonJoel, you may have had the key! Its been 4 hours since Jumbo Frames has been turned of (at 1544 right now), and things are running pretty clean and snappy. Will confirm tomorrow if it stays up! Thanks for the info!
EDIT 12-2-21: @JasonJoel gets the gold star! It has been rock solid and performing beautifully since i removed jumbo frames from that switch. Definitely something to look into code wise at some point. Most people would not have that issue so its a pretty small subset of users. I have another thing to try from @gopher.ny but gonna hold that for if anything happens in the future. I am calling this problem solved! Thanks everyone for the help!
