In iRules, when "GENERICMESSAGE::message create" is called after "reject" command inside "after -periodic", it may cause core. Below is an example iRules. when CLIENT_ACCEPTED { ... omitted ... after 1000 -periodic { ... omitted ... reject GENERICMESSAGE::message create "test" } } This relates to ID 859113.

"GENERICMESSAGE::message create" is called after "reject" inside "after -periodic"


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
