When an iRule is removed from a Virtual Server, especially one with explicitly specified high priority (with "priority" keyword), other iRules on the same Virtual Server may become "invisible" i.e. they are present but some of them are no longer executed. It may affect all the events or only certain types of them. Under certain conditions the defect may even disappear upon removing another iRule, particularly if it has low priority and handles the same event as the one which introduced the problem.
Some or all iRules on given Virtual Servers stop being executed.
Removing an iRule from a Virtual Server.
Restart or reload the configuration. If removing iRules needs to be performed in run-time and it triggers the problem, it can be prevented by having any iRule (even an empty one) for the same event, as the iRule which is going to be removed, but with higher priority e.g. with attribute "priority 1".
