BIG-IP LTM, PEM
Known Affected Versions:
14.0.0, 13.1.0, 13.0.1, 13.0.0
Opened: Apr 25, 2018 Severity: 3-Major
Internally connecting from a parent virtual server to an internal virtual server (IVS) fails, resulting in failure of whatever service was being attempted. This is indicated by the following error message: err tmm1[29909]: 017b0002:3: IVS (connection from parent 172.16.88.20:60109 -> 10.10.10.10:80): Internal virtual server /Common/ivs_name is not ready for connections. Subsequent transactions on the IVS on the same TMM fail.
The transaction in progress succeeds, but the next transaction on the IVS on the same TMM fails, along with the service it was part of. The IVS no longer functions on the affected TMM until the TMM is restarted.
A transaction on a virtual server is in the process of connecting to the IVS internally, while at the same time an iRule is added or modified on that IVS. Note: This issue occurs because of a race-condition, so it occurs intermittently.
There is no workaround other than not changing iRules on an IVS while a transaction on a virtual server is in the process of connecting to the IVS internally. If this occurs after changing the configuration, restart the TMM. Traffic disrupted while TMM restarts.
