AWS client getaddrinfo EMFILE issue
Recently, we introduced AWS Cloud Map for service discovery, primarily to retrieve queue URLs. However, after deployment, we encountered intermittent errors weeks later, logged as getaddrinfo EMFILE events.ap-southeast-2.amazonaws.com. Not all requests triggered this error, indicating a selective issue.
Upon inspection, it became apparent that we were facing a socket timeout problem, a known issue in our setup. The remedy was simple: reusing our existing agent.
