This last year, I've seen a MikroTik CCR1072 switch from long being rock-solid to now having occasional random reboots (from watchdog) or 100% CPU usage, which strangles the BGP process. In the latter case, tools->profile would show the firewall taking 100% of CPU, even after temporarily disabling all firewall filter and NAT rules and connection tracking. Not fun.
MT tech support did not seem super helpful or interested, mostly recommending to disable watchdog (unacceptable on a production router) or to upgrade firmware (without specifying the suspected cause of the problem or nature of the fix). Tried 1 update, that didn't seem to help, have now tried another... On Sun, Dec 20, 2020, 11:38 PM Steven Kenney <st...@wavedirect.org> wrote: > MIkrotik has been rock solid for me for years.
