Continuous reboots after updating to 6.43.1-6.43.2 (RB750Gr3)

RouterOS General

After upgrading to the latest version, my router will not run for more than 1 or 2 days. After a reboot, I find in the log “router rebooted because some critical program crashes”

I reset the router, then imported my settings again. But nothing changed.

Now I’ve done Netinstall, and reconfigured by hand. This time only the most necessary settings.

  • Bridge interface, VLAN
  • DHCP server
  • basic Firewall filters
  • NTP
  • security settings: MAC server, Password changed, Service - SSH, WinBox, WebIf …
  • PPPoE client

This time, however, I noticed that the free RAM is slowly becoming less and less. After 43 hours of running time, only 45 MB of 256MB are free. After a restart, it is about 200MB free, so it was earlier.

ok, I found the problem with the flooded memory. It was because of activated VLAN filtering on the bridge. With today’s version ROS 6.43.4 it seems to be fixed.

Changelog
*) bridge - fixed possible memory leak when VLAN filtering is used;

I watch it, and right now everything is ok. I am now looking over the days, if the router work stable again.
