You may see AP reboots on 64mb RAM access points 7373/7962/7762 in heavy
interference, high density, or large broadcast domain subnets with many small
packets, in versions later than 9.5.3.
It is best to open a ticket with Tech Support, providing your ZD debug log, and
affected AP System Info files, to determine the root cause of unexpected AP
reboots, to compare to known issues.
