Hi Prasad

 

Ideally the timeout value should be higher than the time interval. There is no reason whatsoever to keep it 4 seconds. Please work with your team mates to get it changed. Probably they got confused by the fact that in the default timeout we set i.e., 16 seconds, LTM checks against the monitor for 4 times, they might have set it 4.

 

The timeout should always be higher than the time interval set. If you cannot wait long, probably make it 6 if not more. I dont know what the member status would be in your case. Can you somehow test it and let us know.

 

Another link I got on time interval and timeout discussions .
