csm conn failures

[rays]

Hello Gilles, from you're previous posts I see that conns failures are caused by server sending RST packets or not responding to SYN. I have a situation where we have many real servers and everything appears to work fine, however in most cases I see approx 50% conns succesfull and 50% fail.

Can you explain why that is if the network is showing to be stable? If the server closed a valid connection with a RST rather than a FIN, would that cause the fails to increment? i.e. is it actual connection failures or is it just the server closing a valid connection?

Thanks

a connection is considered a failure if the 3-way handshake does not complete.

So it means if the server does not respond to a SYN or respond with a RESET to a SYN.

Every RESET from the server after the 3-way handshake is not counted as a failure.

Regards,

Gilles.
