Hi,
In the command show serverfarm :
CH01AC03/P-115-A# sh serverfarm NCL_FARM_PROD
serverfarm : NCL_FARM_PROD, type: HOST
total rservers : 6

What does the connections failures field mean ? Is it the number of time the ACE did not receive a SYN-ACK packet within a time window after having sent a SYN ? If it is true, what is the timeout value and can I modify it ?
Thank you

Yves,
the timeout is the embryonic timeout and it can be configured within a parameter-map.
Other reason for this counter to increment is if the rserver responds with a RST.
We have also seen bugs where the client sending a RST results in this counter to increment.
If you can, verify with a sniffer trace in what condition you are before changing the embryonic timeout.
Gilles.
