I do not have these RIC/522 laying around, but installed to the customer location.
Netinstall: http://www.mikrotik.com/testdocs/ros/2.9/guide/netinstall.php?notfound=6&
Please explain how does this method of RouterOS reinstall should fix anything?
How/why does the normal system update isn’t fixing the same issues?
Do you need anything (some logs etc) from the device to pinpoint the source of the issue?
I am experiencing similar problems: having experienced no problems for five months attempting to open a new terminal in Winbox now triggers the following:
Console has crashed or maybe system is completely busy; please log in again.
According to system resources there are 2472.6MiBs free out of 13.8Mib and the CPU is running at about 5%.
Log on this RB112 also reports 36 (thirty-six) disconnects and reconnects between 12.07 and 16.30 today. Another 112 on the same interface reports none.
