Fixed In:

Opened: Dec 22, 2014
Severity: 2-Critical

Symptoms

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.

Impact

Traffic disrupted while tmm restarts.

Conditions

HTTP::payload is used in a non-HTTP iRule.

Workaround

Use i.e. ASM::payload if you want the payload within an ASM event.

Fix Information

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.
