ERROR [io.ver.cor.htt.imp.HttpClientRequestImpl] (vert.x-eventloop-thread-1) {} Connection was closed

[rickbear]

Describe the bug

I have found log entries in my log with the following message: ERROR [io.ver.cor.htt.imp.HttpClientRequestImpl] (vert.x-eventloop-thread-1) {} Connection was closed When I try to trace the error in other logs I can see no other errors. It seems like everything behaves like it should. Though I still wonder if the above message could mean something I should be worried about?

This bug seems to be very similar to my problem on a ConnectionBase instead of HttpClientRequestImpl.

I am using Quarkus 3.8.1 with these dependencies:

io.quarkus:quarkus-smallrye-openapi
io.quarkus:quarkus-rest-client-reactive-jackson
io.quarkus:quarkus-resteasy-reactive-jackson
io.quarkus:quarkus-smallrye-fault-tolerance
io.quarkus:quarkus-arc
io.quarkus:quarkus-smallrye-context-propagation
io.quarkus:quarkus-smallrye-health
io.quarkus:quarkus-opentelemetry
io.opentelemetry:opentelemetry-extension-trace-propagators
io.quarkus:quarkus-smallrye-jwt
io.quarkus:quarkus-cache

Expected behavior

That either there would be no error log or there would be a more descriptive error log which points me in the correct direction.

Actual behavior

This log entry is shown: ERROR [io.ver.cor.htt.imp.HttpClientRequestImpl] (vert.x-eventloop-thread-1) {} Connection was closed for like it seems no particular reason.

How to Reproduce?

It doesn't seem there is a special trigger for the log entry. There are hundreds of calls per minute to this service. So there should be either a lot of entries or none. It appears randomly it seems.

Output of uname -a or ver

GNU/Linux

Output of java -version

Java 17

Quarkus version or git rev

Quarkus 3.8.1

Build tool (ie. output of mvnw --version or gradlew --version)

Gradle 8.6

Additional information

I know uname -a and java -version is not very specific. The code is build and deployed on a system I have no much control of. I can find more specific informations about it if it is of any importance for the issue but it might take a while because of the easter holidays.

[Leokao4Autopass]

I have the same issue. the Error message happened in my production environment, but I can't find any exception stack trace in log, this so hard identify the root cause.
