I've issue with respect to above subject, using knative v1.2.5 istio 1.12.7

Every 20mins we see below error in the queue proxy,

error: "context canceled" knative.dev/key: "test-common-service/test-app-0-0-0" knative.dev/pod: "test-app-0-0-0-deployment-xxxxxxx-xxxxx" logger: "queueproxy" message: "error reverse proxying request; sockstat: sockets: used 44 TCP: inuse 27 orphan 2 tw 20 alloc 593 mem 52 UDP: inuse 0 mem 3 UDPLITE: inuse 0 RAW: inuse 0 FRAG: inuse 0 memory 0

Can someone please let me know how can I fix this.

Thank you!

It looks like you may have requests which are hitting request timeouts in the queue proxy. What is your typical request latency, and what is the Revision timeoutSeconds set to?

It's also possible that istio is cancelling (resetting) some of the TCP connections to the queue-proxy, but that seems unlikely.

  • Hi, Thanks for taking time and replying, revision-timeout-seconds: "300" # 5 minutes and we are getting that error after 20mins.... It will run for 20mins and throw that error the it will start running for another 20mins and the samething. Thanks – jagannath shetagar Jul 19 '22 at 09:49
