Some connections through a virtual server using SSL persistence hang and cause a high CPU condition in tmm.
Large increase in CPU usage on the box and a percentage of SSL connections through the virtual server are delayed and eventually reset
This occurs only when SSL persistence is configured as the default persistence profile, and there is a fallback profile of either source_addr or dest_addr.
None.
SSL Persistence Profile now operates correctly, and does not cause high CPU usage.
