TMM restarts when sending traffic through a SOCKS virtual server that has an attached iRule that uses certain blocking commands.
Unexpected tmm restart. Traffic disrupted while tmm restarts.
Virtual server has a SOCKS profile, and an iRule which triggers on the SERVER_CONNECTED event. If the iRule uses commands that block, tmm might restart.
Avoid adding iRule on the SERVER_CONNECTED event, or avoid using certain iRule commands which do not complete immediately, such as 'after', 'table', 'session', and others.
TMM no longer crashes when using SOCKS profile and serverside iRule parks.
