Connection Not Redirecting to HTTPS After Initialization.
Some SSH clients and web browsers automatically lose the SSH or HTTPS
connection when the HSM initializes or when the wrong password is entered three
times. If a user enters the wrong password three times via SSH, attempting to log back
into the appliance via HTTP will result in an error message because the connection
will not redirect to HTTPS. In these cases, the administrator must manually reboot the
appliance by powering it off and on.

Appliance May Become Unresponsive
A C660, C670, X1060, or X1070 appliance may become unresponsive after
processing a high amount of message traffic with large attachments over an extended
period of time. This issue requires the work queue, scanning engines, and other
AsyncOS features to be handling a constant high level of traffic in order to create the
excessive memory usage that causes the appliance to become unresponsive.
