Hi,
How does CSS check the availability of the server service? How much data it send? Size?
Reason because I see the attached errors in AIX, there are tons of them. I suspect the "error" doesn't close the connection properly which then causes intermittent connection from the client as there are not much resources in the server.
192.168.1.1 is CSS
Thanks,

The exact answers to your questions depend on the configuration of the CSS. But a normal configuration would see the CSS using TCP port connections every so often to check the status of the service. In my experience the hosting server sees the connections just like how your host system sees them - as aborted TCP socket connections.
As for the keepalive causing problems with the server and for the client accessing the application, I've never seen that. You can turn off keepalives though in the configuration to test that probably.

Hi,
Thank you for replying. Do you think there's a problem with the SERVICE or SCRIPT below that cause the error?
Here is the config for 20081 (20082 and 20083 is similar)...
-------------SERVICE_20081-----------------
service client1-to-server1
ip address 192.168.1.20
port 20081
keepalive type script ap-kal-tcp20081 "192.168.1.20"
keepalive retryperiod 15
keepalive frequency 120
keepalive maxfailure 2
active
service client1-to-server2
ip address 192.168.1.21
port 20081
keepalive type script ap-kal-tcp20081 "192.168.1.21"
keepalive frequency 120
keepalive retryperiod 15
keepalive maxfailure 2
active
-------------SERVICE_20081-----------------
-------------SCRIPT_ap-kal-tcp20081-----------------
if ${ARGS}[#] "NEQ" "1"
echo "Usage CUSTOMER \'Hostname\'"
exit script 1
endbranch
! Defines:
set HostName "${ARGS}[1]"
! Connect to the remote Host
set EXIT_MSG "Connection Failure"
socket connect host ${HostName} port 20081 tcp 2000
! Send the GET request for the web page
set EXIT_MSG "Send: Failed"
no set EXIT_MSG
socket disconnect ${SOCKET}
exit script 0
-------------SCRIPT_ap-kal-tcp20081-----------------
Thanks,
