Hey folks We are having increased flaky failures for the past one day.
Mostly, streams upgrade tests (:streams:upgrade-system-tests-20:unitTest) are failing with org.gradle.internal.remote.internal.ConnectException: Could not connect to server [90d54b62-a664-438e-b241-20847ead1eab port:34765, addresses:[/127.0.0.1]]. Tried addresses: [/127.0.0.1]. [2023-06-15T14:50:31.779Z] at org.gradle.internal.remote.internal.inet.TcpOutgoingConnector.connect(TcpOutgoingConnector.java:67) And other network related tests are failing with errors such as java.net.ConnectException: Connection timed out at java.base/sun.nio.ch.Net.connect0(Native Method) at java.base/sun.nio.ch.Net.connect(Net.java:579) at java.base/sun.nio.ch.Net.connect(Net.java:568) at java.base/sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:588) at java.base/java.net.SocksSocketImpl.connect(SocksSocketImpl.java:327) at java.base/java.net.Socket.connect(Socket.java:633) at java.base/java.net.Socket.connect(Socket.java:583) at java.base/java.net.Socket.<init>(Socket.java:507) at java.base/java.net.Socket.<init>(Socket.java:319) at org.apache.kafka.common.network.PlaintextSender.lambda$new$0(PlaintextSender.java:30) These stack traces probably hints at some infra problem to me? I will take a deeper look tomorrow in my day time but meanwhile, if someone gets a chance, please try to debug!
