Recently, one of our soon to be deployed serverfarm stopped responding to requests, because it has reached the max-conn limit.
The strange thing is, the serverfarm is usually under very little load.
Here are some dumps of the CLI
CSM01#sh mod csm 7 vservers name ipc2.web.http config
IPC2.WEB.HTTP, type = SLB, state = OPERATIONAL, v_index = 64
virtual = 20.254.127.24/32:81 bidir, TCP, service = NONE, advertise = FALSE

max parse len = 2000, persist rebalance = TRUE

conns = 1, total conns = 76532

As you can see, the counter has maxed out, even thoguh the connections table is blank.
Any help is much appreciated.
