java.net.ConnectException: Connection refused

Open carlislk opened this issue 6 years ago • 0 comments

After starting use of this module we are seeing alot of java / kafka errors from linkerd.

java.net.ConnectException: Connection refused WARN 0620 18:19:05.201 UTC kafka-producer-network-thread | producer-1: Error in I/O with localhost/127.0.0.1 at java.lang.Thread.run(Thread.java:748) at org.apache.kafka.clients.producer.internals.Sender.run(Sender.java:191) E 0620 18:18:52.913 UTC THREAD36 TraceId:b34e5cf7b68e40ef: service failure: com.twitter.finagle.CancelledConnectionException

Config: telemetry:

  • kind: io.zipkin.http host: <Collector-Domain>:9411 initialSampleRate: 0.02

Where Collector-Domain.com points at an AWS NLB and targets are jaeger-collector containers running in ECS.

This issue happens intermittently on hosts and seems to only be solved by a restart of linkerd. Any insight would be appreciated.
