Increased memory usage in tmm.
The memory allocated for congestion control is not freed.
TCP::congestion highspeed iRule is executed for the TCP connection. The issue is only observed for highspeed congestion control.
If it is desired to use highspeed congestion control under some conditions, it is possible to start with highspeed by choosing highspeed congestion control in the TCP profile and switch to other desired congestion control when condition does not hold. With this workaround, once congestion control is changed to something other than highspeed, it is not possible to switch back to highspeed again.
Improved memory utilization while using TCP::congestion iRule.
