Opened: May 03, 2018
Severity: 2-Critical

Symptoms

In very rare circumstances, connections that use virtual targeting virtual server and time-wait recycle result in a connection being improperly reused.

Impact

A connection might be reused even though it is a new one. TMM can crash and restart. Traffic disrupted while tmm restarts. Note: This is an extremely rare issue.

Conditions

Virtual server targeting virtual server (usually occurs in an iRule) with time-wait recycle being used on the virtual server's TCP profile. Note: This is the default value, so any virtual servers defined internally are using it.

Workaround

None.

Fix Information

This issue has been fixed.
