When processing SSL handshakes in the crypto acceleration hardware, a BIG-IP 2000 or 4000 platform might experience a TMM core.
Traffic disrupted while tmm restarts.
This can occur when processing SSL handshakes in the crypto acceleration hardware. The issue is very unlikely to be seen other than on BIG-IP version 11.6.0 HF5 or on version 12.0.0 base install.
This issue has no workaround at this time.
The crypto acceleration hardware driver for the 2200/4200 has been fixed to avoid memory corruption.
