sc-status is a protocol status code from the appliance to a client.
The usual results for
sc-status are the following
HTTP response codes:
0 (zero) indicates that the ProxySG appliance did not have the chance to send the status code due to a possible connection reset. If you are logging
s-action on the same log line, you might see
TCP_NC_MISS_RST that could correlated to
sc-status 0.
A packet capture taken when the
sc-status=0 logging is happening can also help.
