The HTTP::payload command could cause the TMM to crash if invoked when HTTP had already started egressing data to other filters. This could only happen if HTTP::payload was used in a non-HTTP event.
Traffic disrupted while tmm restarts.
HTTP::payload is used in a non-HTTP iRule.
Use i.e. ASM::payload if you want the payload within an ASM event.
HTTP::payload will no longer cause a TMM crash if invoked in a non-HTTP event. Instead, an error will be returned to the iRule.
