I decided to move from 6.5 to 6.27 all my devices (1100AHX2). I have found some MAJOR issues (configuration corruption and device softbrick)upgrading to latest ROS (atm 6.27 stable). To replicate this issues i setup testing enviroment by using huge ammount of queue tree entries (about 2000). I using /import command for importing testing configuration. First of all i started using clean instalation of v6.27. During import of configuration the import process hanged with console message:
Code: Select all
action timed out - try again, if error continues contact MikroTik support and send a supout file (13)Code: Select all
> /system reboot
Reboot, yes? [y/N]:
y
system will reboot shortly
Rebooting...
Stopping services...
failed to stop racoon: std failure: timeout (13)
failed to stop ppp: std failure: timeout (13)
failed to stop wireless: std failure: timeout (13)
failed to stop route: std failure: timeout (13)After hardware reset(power unpluging) the device stayed softbricked (all ethernet ports down!) only rs232 console responsible. another /system reboot did the same as before. I tried various commands include /export whish exported nothing. Only reset to default /system reset-configuration (via rs232 console) followed by hardware reset (power unpluging) made the device responsible again. Importing the script kill it again.
So i downgraded the device to my fellowed 6.5, imported testing script (all ok). Then i upgraded to 6.27. The device has not survived the reboot with the same symptoms i described before. So i decided to start bisection from v6.5 to v v6.27 and i have found than upgrade from v6.23 to v6.24 killing the device.
It exactly mean than a change in v6.24 killing my configuration. Since its associated with queue tree maybe is it this ?
