--- Comment #3 from Matafagafo <matafag...@yahoo.com> --- (In reply to Mark Thomas from comment #1) > Steps to reproduce from a clean install of the latest stable 9.0.x (or any > other currently supported major version) release please. A Tomcat 9.0.65 configured to enable HTTP/2, using the following connector configuration in server.xml <Connector port="443" protocol="org.apache.coyote.http11.Http11Nio2Protocol" SSLEnabled="true" address="0.0.0.0" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" SSLCertificateFile="/etc/tomcat9/xxxxx.com.crt" SSLCertificateChainFile="/etc/tomcat9/chain.pem" SSLCertificateKeyFile="/etc/tomcat9/xxxxx.com.pem" SSLPassword="xxxxxxxxxx" SSLCipherSuite="ALL:!ADH:!SSLv2:!EXPORT40:!EXP:!LOW:!aNULL" compression="on" > <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" compression="on" overheadCountFactor="0" overheadContinuationThreshold="0" overheadDataThreshold="0" overheadWindowUpdateThreshold="0" readTimeout="2000000" /> </Connector> With HTTP/2 enabled, spurious *Unable to write to stream once it has been closed* are generated, as you can see on attached log file. With HTTP/2 disabled the errors don't occurs any more. I want to enable HTTP/2 but with this errors it is impossible. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
