NimbostratusHealth Check failing because server cannot accept more TCP connections
Hi ALL,
I have a server pool with 2 netcool servers listening on port6068. It is monitored by a custom TCP monitor on TCP6068. Now the Pool is marked down until the server admin closes active TCP 6068 sessions. It seems only 1 TCP 6068 connection is allowed on the server ( not sure why ). Is there another way we can health monitor the servers effectively? (avoiding using icmp ).
Thanks Harps

You can try with content check monitors eg: http or https.
Harps_VIrdee_SiHi Raghavendra,
Thanks, unfortunately there are no web services running on the server. so content check won't be an option :(

Ok. can you check connection configurations under advanced pool section, see any limit is configured.

Hi,
Connection limit is set to 0. Think its more on the server side limiting the connections.
is there any monitoring the F5 can do at command line level on the sever?

Try with TCP_half monitor and see still connections are closing.

still seeing the same issue with TCP_HALF_OPEN

Can you please paste your configurations here and also tcpdump packet capture details.
