Symptoms
After rebooting with an HSM configured, you notice the first few handshakes fail, with the following error signature in /var/log/ltm:
warning tmm3[13085]: 01260009:4: Connection error: info tmm3[13085]: 01260013:6: ssl_hs_vfy_sign_srvkeyxchg:9921: sign_srvkeyxchg (80)
1260013:6: SSL Handshake failed for TCP <src> -> <dest>
Impact
The initial SSL connections will fail, then normal operation will resume.
Conditions
This occurs on the first few connections after reboot when an HSM is configured, and seems to occur if the device does not immediately pass traffic after reboot.
