When SIP iRule events fire multiple times, it may execute rules which may no longer present be in the running configuration.


Rule will not function as anticipated. Impact to traffic will vary.


Configure a virtual with a SIP profile and an iRule applied via a profile (e.g. a persistence profile). The iRule must handle SIP related events. When the rule is modified, both the old and new versions of the SIP related rules will fire.


Apply the iRule directly, rather than via a profile.
