Severity: 3-Major


Under certain circumstances tmm can reorder or omit HTTP data segments when they are received while processing an iRule which is parked.


Data corruption or loss can occur.


- HTTP iRule execution suspended, e.g., waiting for a table command to return. - Ingress data is processed during this state.


There is no workaround other than not using iRule suspend commands in HTTP_* events.

Fix Information

tmm now handles ingress data correctly when in the parked iRule state.
