tool profile console at 95%

RB411AH Ros 5.19
CPU locked at 100%
profile shows console using about 95%
Reboot clears it up for a while.
I saw this about 10 days ago and rebooted. Problem went away.
Now it comes back after about 10 minutes.
Any suggestions



edit - Tried to run a backup from terminal

> system script run Backup 

Console has crashed; please log in again.

Never seen that before

try upgrade to 5.25
http://download2.mikrotik.com/routeros/5.25/routeros-mipsbe-5.25.npk

then
/system routerboard upgrade
/system reboot

It appears as if it locks up during the backup process.
I had the backup on a schedule. Disabled it for now.
Waiting to see if it continues to work with backup disabled.

This is a production AP so upgrading doesn’t really excite me right now. Too stormy out to replace if upgrade doesn’t go well.
Getting a replacement configured right now.
