This applies only to Stratos 2200s and 4200v platforms. Resetting connections with compressed content might not perform a complete clean-up.


The incomplete reset results in orphaned xfrags and active_requests growing without bound. New requests on the affected virtual server will stall.


Manifests when there is a reset on the flow. The resets slowly accumulate xfrags and active_requests.
