ER605 Needs weekly Reboot Issue - does it have a memory leak?
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
So I have had my fleet of ER605's on a weekly reboot diet now for over a year. Because if I don't do that, they eventually permanently lose contact with the Controller (hardware or software). I have recently started experimenting with LibreNMS and I've found a few things, but the most interesting was the continuous ramping of memory usage over time. I only have about 4 days since I set this system up (running in a Docker on my Synology) but here's what I see. I am curious if this is normal, or if the platform has a memory leak.

@Fae Please let me know if the support team needs anything else. I had a dozen router disconnects today...I've leaving it up as long as I can, but if i lose control, I will have to reset this as it's in production--and it takes 3-5 weeks to get back to the disk starvation state.

Router is now hard disconnected. It looks like a process has crashed, most likely omadad (the Omada controller application running on router). You can see the moment it gives up, the CPU load drops right down and there is a decrease in memory consumption as well....to me, that's a process that just went Pffssst!
The white vertical stripes you see below in the middle graphs (previous week) are temporary disconnects, ie where the router became non-responsive on it's IP (no Omada access...but VPN, SSH and SNMP are functioning fine)
