If a virtual server has an iRule performing SSL payload processing in CLIENTSSL_DATA, TMM fails to process or forward an ingress TCP FIN from a client, leaving the connection in a zombie state until it eventually idles out.
Unexpected growth in the number of connections idling on a virtual server leads to memory pressure.
The issue occurs only when SSL::collect is used in CLIENTSSL_DATA when CLIENTSSL_DATA { log local0. "." SSL::release SSL::collect }
None.
