Clearing connections on a backup LTM

The VIP is actually load balancing squid proxy requests on port 8080. We use a health monitor to telnet to port 8080 of the node and do a simple http HEAD query on a particular URL and the heath check succeeds if it gets back a 200 response.

I've tried deleting the connections to the node with "b conn server 210.15.x.x delete" but it still shows a high connection count. To me they just look like stale mirrored connections left over from the Primary LTM when the VIP on there had it's little heart attack.

Before:

[root@f5-2-manage:Standby] config b node 210.15.x.x

NODE 210.15.x.x up session enable

| (cur, max, limit, tot) = (6415, 7209, 0, 133213)

| (pkts,bits) in = (0, 0), out = (0, 0)

| requests (total) = 0

Run Command:

[root@f5-2-manage:Standby] config b conn server 210.15.x.x delete

After:

[root@f5-2-manage:Standby] config b node 210.15.x.x

NODE 210.15.x.x up session enable

| (cur, max, limit, tot) = (6443, 7209, 0, 133417)

| (pkts,bits) in = (0, 0), out = (0, 0)

| requests (total) = 0

Any more ideas?

Thanks.
