"epoll_wait(..) failed: Function not implemented" on Ubuntu 22.04 #12343

lackovic · 2022-04-27T12:08:37Z

Expected behavior

Running an application with some exposed endpoints, when you call an endpoint you get a response back.

Actual behavior

Works fine in Ubuntu 20.04, but in Ubuntu 22.04 - with any service and any endpoint - I get the following error:

io.netty.channel.epoll.EpollEventLoop : Unexpected exception in the selector loop.
io.netty.channel.unix.Errors$NativeIoException: epoll_wait(..) failed: Function not implemented

reactor.netty.http.client.HttpClient USER_EVENT: SslHandshakeCompletionEvent(io.netty.handler.ssl.SslHandshakeTimeoutException: handshake timed out after 10000ms)

I think I have an idea… let me investigate

Motivation: Its possible that while there is an epoll_pwait2(...) system call it is not implemented and so fail with ENOSYS. Modifications: Check if we can actually use epoll_pwait2(...) and it not fails due not implemented. Result: Fixes #12343

lmcdasi · 2022-04-30T00:36:23Z

Sorry - I do not think you can wait until 4.1.77 is released.
Because of the way maven applies the dependency at build time, I think this is a blocker/critical issue for many projects.
I need now to verify which dependency introduced 4.1.76 even tough I had 4.1.72.
With all due respect, it became a nightmare ...

chrisgleissner · 2022-05-03T06:05:26Z

We are blocked from upgrading from Spring Boot 2.6.6 to 2.6.7 since the latter upgraded to Neety 4.1.76 which introduced this issue, see https://github.com/spring-projects/spring-boot/releases/tag/v2.6.7

I see that you are half-way through implementing all bug fixes and features planned for Netty 4.1.77. Due to the impact of this issue, is there any chance you could release an interim bugfix release 4.1.76.1 or alternatively release 4.1.77 early.

Thanks.

normanmaurer · 2022-05-03T06:40:27Z

We will cut a release tomorrow

I was using Ubuntu 22.04 LTS (Jammy Jellyfish) and kept getting this error. Make sure you pin to Ubuntu 20.04 (Focal Fossa) and avoid this error, until the issue is resolved!

I am using Ubuntu 22.04 LTS: I am not having this issue since I updated my project to use Spring Boot 2.7.0, which includes Netty 4.1.77.FINAL, which had this issue fixed.

Ubuntu Jammy/22.04 netty package and the currently used Mojang netty version are incompatible. Downgrading until a fix is released. netty/netty#12343 resolves #21

We are using netty-common - 4.1.77.Final and spring boot 2.6.7 and started running into this issue. We have been using this configuration for the past year and it started giving us error 2 days back.
Any fix or workaround for this?

chrisvest · 2023-08-30T21:04:48Z

The important module is transport-native-epoll – maybe you're using an older version of that module. Make sure all Netty modules are of the same version. Try upgrading to the latest. If there are still problems, open a new issue because it'll be a new problem.

We appear to be hitting netty/netty#12343 Will investigate an upgrade to Netty in a future PR

We appear to be hitting netty/netty#12343 Note that this defect only appears to happen when running inside of the AWS path to live environment. When run locally, the adaptor doesn't run into this codepath. Will investigate an upgrade to Netty in a future PR

The current build is erroring with: > io.netty.channel.unix.Errors$NativeIoException: epoll_wait(..) failed: Function not implemented This is because of netty/netty#12343 By switching to the version of Gradle we use within the repo we also downgrade Ubuntu to Focal as a side-effect.
