Hi,

We keep receiving these messages, can someone tell me what this refers to please?

The Critical message is:

An application fault occurred: ('egg/coro_ssl.py _non_blocking_retry|118', "<type 'exceptions.OSError'>", '[Errno 0] Error', '[egg/smtp_client.py run|879] [egg/smtp_client.py _run|958] [egg/coro_ssl.py close|216] [egg/coro_ssl.py shutdown|196] [egg/coro_ssl.py _non_blocking_retry|118]')

Version: 7.8.0-360

Such an application fault is generally caused by an issue where a TLS session fails to close properly. In this scenario, the email does deliver successfully, but can produce an application fault. In general, these application faults do not indicate a problem with the appliance, and shall be suppressed in a future release of AsyncOS.

With running 7.8.0 - which shipped on the appliance, you may benefit to upgrade to 8.0.1-023, or open a support request to have the appliance properly provisioned for 8.5.6 FCS, which may help to correct seen TLS issues, such as this.

I hope this helps!
