When an HTTP profile is configured in transparent mode, but has a nonexistent iRule attached to it, then tmm will crash.
TMM halts and restarts. Traffic disrupted while tmm restarts.
-- There is iRule. -- Proxy is transparent. when HTTP_PROXY_REQUEST { after 1000 } -- Change configuration from explicit to transparent while the system is processing in the after command. -- There is then an attempt to use a configuration that does not exist.
This is incorrect configuration. Either detach the iRule or configure the profile in a mode other than transparent.
Incorrectly configured proxy types from TMOS installations of earlier versions will be corrected at upgrade time. A warning will be logged that describes the change made.
