Outbound routing creates connections that never clear

Hello:     I installed my shiny new GTM/LTM last Sunday and things looked pretty good until yesterday afternoon.     I noticed on the Performance->Active Connections graph that there was a...

    Aaron is right, this pattern smacks of indefinite reaper timeout. Check to make sure the timeout on the tcp profile isn't set to 0/indefinite.

Is there a corresponding upward trend in memory consumption along with the increasing connection count? What was the TMM memory usage at when the restart happened?

Out of curiosity, on the wildcard VIP's fastL4 profile, what is the timeout set to? I hope not indefinite. If you look at the 'b conn all show all' output, what are the majority of the connections you see? What are the idle count and idle timeout values for the connections?

In this example, the idle count is 11 seconds and the timeout is 300:


VIRTUAL 1.2.3.241:ssh <-> NODE 1.2.3.246.241:ssh   LOCAL
    CLIENTSIDE 2.1.45.39:squid <-> 2.81.246.241:ssh
        (pkts,bits) in = (55, 58928), out = (47, 53584)
    SERVERSIDE 2.1.45.39:squid <-> 2.81.246.241:ssh
        (pkts,bits) in = (47, 53584), out = (55, 58928)
    PROTOCOL tcp   UNIT 0   IDLE 11 (300)   LASTHOP 4094 00:fc:0f:2c:bc:00
