TABLE 5 HTTP keep alive statistics
This field... Displays
Allocated from pool The number of instances when a server port was allocated
from the Keep-Alive pool.
Freed to pool The number of instances when a server port was freed to
the Keep-Alive pool.
Total TCBs in list
(appears in two locations)
The total number of Keep-Alive connections received by
the ServerIron ADX.
