Seen similar behavior when your router is starting to run out of memory and the Linux kernel is starting to shut down services on you, or there is some other memory related issue with the board.
Might want to check your memory consumption on the router and see if your running any layer 7 firewall rules or Web proxy which both can suck up memory like you had unlimited amount of ram.

It's an RB433 running ROS 6.20. Recently, it began behaving a bit oddly in that it will stop responding to management request e.g. Winbox times out, telnet and SSH connect and ask for a username/password, but fail after about 60 seconds of waiting (for locally provisioned user e.g. admin). The unit still passes payload traffic to/from the customers, and responds successfully to SNMP queries. If I disable the uplink interface facing the device, the ping watchdog will successfully trip, reboot the device, and it will respond to management requests again... until it stops - 'days' later.
