Known Affected Versions:
21.1.0, 21.1.0.1, 21.1.0.2, 21.1.0.3
Opened: Oct 13, 2026 Severity: 3-Major
Connections are RST by tmm with a reset-cause of "No available SNAT addr" even though the configured snatpool has members.
Client connections might be RST.
-- A full config-sync was performed that removed a snatpool. -- The snatpool is recreated with the same name and includes one or more members that were in the snatpool when it was deleted. -- The snatpool is applied to a virtual server.
Restarting tmm will clear the issue if it occurs. # tmsh restart sys service tmm Note that if the BIG-IP is active, restarting tmm will cause a traffic interruption.
