9.8(2.38)

Description (partial)

Symptom:
ASA in multi context configuration, even though the "logging permit-hostdown" command is set, it doesn't disable the feature to block new connections when a TCP-based syslog server is down.

Regardless if the command is in placed, ASA drops new conns and produces "Disallowing new connections" messages.

Conditions:
ASA in multi context configuration, with the "logging permit-hostdown" command set, and external syslog server setup using TCP.

Unfortunately, this problem has not been reproducible yet in our local TAC labs.
