I am currently facing an issue in my load environment during the load testing. The description of the issue is given below,
We have a Jersey REST application which is being guarded by a GO application. GO app validates the browser cookie and creates a single host reverse proxy and serve the request if its a valid one, Initially we got the below error http: proxy error: dial tcp HOSTNAME:PORT can't assign requested address Even after upgrading it to 1.6, the same issue is happening but GO App log shows the below error "http: proxy error: net/http: request canceled" I've enabled the DisableKeepAlives and performed the load testing and the same issue is happening, Now Go app shows the below errors. http: proxy error: dial tcp HOSTNAME:PORT: i/o timeout http: proxy error: net/http: request canceled Code snippet for creating proxy is given below var proxy = httputil.NewSingleHostReverseProxy(proxy_url) http.DefaultTransport.(*http.Transport).DisableKeepAlives = true We use proxy.ServeHttp after we validate the request. Normally the above proxy error is not occurring suddenly but it occurs after 2 or 3 hours after which load testing is started After disabling keep alive connection, we see lots of TCP connecion in TIMED_WAIT state but its not getting closed but the application is hanging and see the proxy error in the log. So we have to either call https://golang.org/pkg/net/http/#Transport.CloseIdleConnections or increase MaxIdleConnsPerHost to some higher value to fix this issue. The same test cases were working fine in the past but its failing now suddenly. Appreciate your help. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
