Hi,
yesterday I have add a new AP, R710, and some hours later the complete unleashed is rebooting.
i See in the log very often this backtrace:

the Unleashed have a uptime from 80 days an in the smtp monitoring I can see the memory is full:
the firmware version is 200.15.6.212.14.
any ideas?
best regards
