There is a chance, when HTTP in Fallback mode, that the HTTP filter will send an Abort event to the TCP filter (causing tear down) prematurely while the Aborting that was triggered by the upper filter/proxy is occurring. TMM may crash when this happens.
Traffic disrupted while tmm restarts.
It is not known exactly what conditions trigger this, but it has been known to occur when issuing HTTP::respond in the LB_FAILED event in an iRule, and it has been seen only rarely.
None.
Fixed a rarely occurring tmm crash that might be related to issuing HTTP::respond in the LB_FAILED event in an iRule.
