Random "The Network Adapter could not establish the connection" errors
Has anyone experienced random "The Network Adapter could not establish the connection" connect error? This is for a 11204 database & listener.
We have a daily job that will make a few hundred connections or over 900 connections with a minute or 2 then fail with the error below or it will fail on the very first record and then we restart the job and it runs fine. But both of these are very random, like only once or twice a month.
Application log showing successful connection then error:
