Description (partial)

Following Application fault received from the Cisco Email Security Appliance.
An application fault occurred: ('egg/ _non_blocking_retry|140', 
"<class 'sslip.Error'>", "(336195711, 'error:1409F07F:SSL 
routines:SSL3_WRITE_PENDING:bad write retry')", '[egg/ run|885] 
[egg/ _run|964] [egg/ close|238] [egg/ shutdown|218] 
[egg/ _non_blocking_retry|140]')
The app-fault occurred when the ESA was closing an SSL/TLS socket on the incoming mail side -- 
presumably when accepting an email over a TLS connection. The error indicates that the 
ESA's SSL library thinks the TLS packet received from the email client was malformed.

Incoming TLS connections to the ESA can cause the Application Fault error message.
The problem is occurring when one of the following ciphers is selected by ESA
