The BIG-IP system does not reconnect to SafeNet HSM if the connection is interrupted. That means that SSL connections that utilize a key stored on the network HSM fail.
When this occurs, the system experiences traffic interruptions for SSL connections that utilize a key stored on the network HSM until manual corrective action is taken.
This occurs when the BIG-IP system is configured to use a SafeNet network HSM and the connection between the BIG-IP system and the network HSM is interrupted.
To work around this issue, restart the pkcs11d process using the command 'tmsh restart sys service pkcs11d'.
The BIG-IP system now reconnects to SafeNet HSM if the connection is interrupted, so connections continue as expected.
