Hi, I wanted to get a better understanding of of the nuances of ALLOW_NEW_CONNECTIONS_TO_QUEUE in a high volume burst scenario.
MX_MAXIMUM=20 MX_QUEUE_TIMEOUT=300 Assume a burst of emails comes in and all 20 md processes are busy working. 1) What should the 21st and higher connecting clients experience? 2) Is there a configurable limit to the number of queued connections? 3) What's the downside of letting the connections queue other than holding open more TCP connections? 4) Any other tips on the settings you use in production? The reason I'm asking is because we recently had a burst of traffic that caused the IO on our server to go up to a point where everything became unresponsive for a couple minutes. We had our MX_MAXIMUM set to 110. _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
