Known Affected Versions:
13.1.0, 13.0.0 HF1
Opened: Sep 09, 2016 Severity: 2-Critical
Occasionally, the BIG-IP will send a TCP RST in response to an initial SYN with the reset cause "No local listener". This does not affect subsequent connections from the client, so they are likely to succeed. The reset cause for a packet can be logged by setting the DB variable TM.rstcause.log to enable. The reset cause can be sent in the RST packet by setting the DB variable TM.rstcause.pkt to enable.
The attempted connection is reset. Subsequent attempts are likely to succeed.
A virtual server is configured to use TCP and a client initiates a connection.
The icr_eventd daemon was updated to use TCP connections more efficiently.
