Fixed In:

Opened: Jul 17, 2017 Severity: 2-Critical
A race condition between SSL forward proxy lookup forged certificate and the server SSL handshake could cause the invalid forge certificate state with a NULL hash algorithm, causing tmm panics.
TMM generates a core file. Traffic disrupted while tmm restarts.
-- Two-unit SSLo deployment. -- Transparent or explicit proxy modes.
There is no workaround at this time.
This race condition no longer occurs, so the issue no longer occurs.
