SSLEngine closed already exception triggered by reload

November 05, 2018 09:14AM
I noticed that if I setup a simple scenario where a client is making concurrent requests on a server with nginx configured as a reverse proxy and SSL traffic termination endpoint, if I trigger a reload with 'nginx -s reload' mid requests, often times the client will throw an 'javax.net.ssl.SSLException: SSLEngine closed already
at io.netty.handler.ssl.SslHandler.wrap(...)(Unknown Source)' exception.

I'm using Scala with the Play framework, which uses netty under the hood.

Is there any configuration that could avoid these exceptions being thrown?
I cannot reproduce it using for example using Play to serve HTTPS, so I can possibly rule out a problem in the client and think it is a problem with nginx?

Thank you.
