In iRules, when "reject" is used inside "after -periodic" and it is followed by "GENERICMESSAGE::message create". It may trigger a tmm core. Below is an example iRule. when CLIENT_ACCEPTED { ... omitted ... after 1000 -periodic { ... omitted ... reject GENERICMESSAGE::message create "test" } } This relates to ID 859721
Traffic disrupted while tmm restarts.
- "reject" is used inside "after -periodic" - it is followed by "GENERICMESSAGE::message create"
There are 2 possible work-arounds - use "return" command after "reject" to exit after script immediately after "reject" command is invoked - add routine to cancel the after in CLIENT_CLOSED event
Using "reject" iRules command inside "after" no longer cause core.
