Hello, i have a problem with EAS Build.

I’m running the command:
“eas build --platform android”

Linux-x64
EXPO SDK: 45
EAS-CLI: 2.1.0
EXPO-CLI: 6.0.6
Workflow: Managed

Apparently the problem is not in the project configuration, since I tried to run it with a version that worked before and it still didn’t run giving the same message.

See logs for the “Run gradlew”:

This doesn’t seem to me to be an error in my project:
“[stderr] error EMFILE: too many open files, open '/tmp/metro-cache…”
and yes in “eas build”

Can you try adding

  "scripts": {
    "eas-build-pre-install": "sysctl -w fs.inotify.max_user_watches=524288",

in your package.json?
Note this is just to test, it will probably break iOS build, you will need to check for platform to use that as a workaround.

I added this line in my package.json scripts as suggested

{
   ...
  "scripts": {
     ...
     "eas-build-pre-install": "sysctl -w fs.inotify.max_user_watches=524288",
     ...
  }
  ...
}

But I got the build error in “Run gradlew” apparently the error persists:

[wkozyra]

sorry forgot about sudo

sudo sysctl -w fs.inotify.max_user_watches=524288

[nappsolutions]

The “Pre-install hook” ran successfully with “sudo”

[nappsolutions]

But the “Run gradlew” the error persists

[nappsolutions]

I did some research, it seems that it is related to this, but I couldn’t change it.

[nappsolutions]

I have no idea what could be happening, I tried to change the limits but it seems that the configuration is not maintained between the steps

@nappsolutions did you find the solution, we are facing the same issues

[bagwalamurtaza]

@ wkozyra any thing else we can do to get this fixed, we are blocked due to this.

[wkozyra]

We are working on a fix, in the meantime you can try switching to newer ubuntu, it seems that low limit to nofiles is only happening on ubuntu 18

note that sudo sysctl -w fs.inotify.max_user_watches=524288 in preinstall hook might still be necessary.

@wkozyra Thanks a lot, I used the latest image and it worked for us.

In eas.json added the latest image for the preview profile

 "preview": {
      "distribution": "internal",
      "android": {
        "buildType": "apk",
        "image": "latest"
      },
}

Switching to newer ubuntu (from ubuntu-18.04-jdk-11-ndk-r19c to ubuntu-20.04-jdk-11-ndk-r21e) worked for me even without the Pre-install hook in the package.json

{
   ...
  "scripts": {
     ...
     "eas-build-pre-install": "sudo sysctl -w fs.inotify.max_user_watches=524288",
     ...
  }
  ...
}

Just changing the eas.json solved it for me

{
  ...
  "build": {
    ...
    "profile-name": {
      "android": {
        "image": "default"
      },
      ...
    }
    ...
  },
  ...
}

As they are already working on a fix I will keep this temporary solution…

Thank you very much to you and all of the Expo Team.
