When netHSM key is used, the first few SSL connections fail after tmm restart.
The first few SSL connections fail. Subsequent connections recover.
-- A netHSM key is used. -- A tmm restart occurs.
To work around this: -- Wait a few seconds after tmm restart finishes. -- Manually restart pkcs11d.
The system now automatically reinitializes PKCS#11 APIs after seeing failures. This allows the netHSM-based SSL traffic to resume immediately after tmm restarts.
