Encountered EventSource error: Operation not permitted (select/poll failed) about java-server-sdk

[levlaz]

Hey Brett,

Could you let me know which version of Java you are using?

Do you also have any sort of sample code that we can use to try to reproduce this?

[levlaz]

Brett, could you also run this with DEBUG logs enabled? https://github.com/launchdarkly/java-client#logging

If you have any sensitive info in the logs feel free to email them to me instead of posting here. [email protected]

Hi @levlaz ,

Thanks for the quick response! We are running Java 1.8.0_74. I will try to enable debug logging and see if I can get a stack trace for you. I did try this previously as it looks like the LaunchDarkly client only logs stack traces with debug logging enabled. I tried enabling "log4j.logger.com.launchdarkly=DEBUG", but that didn't seem to work. Here is some sample code we are running:

public class LaunchDarklyClientProvider implements Provider<LDClient> {

    public static final String API_KEY_CONFIG = "LAUNCHDARKLY_SDK_KEY";

    private final LDClient ldClient;

    @SuppressFBWarnings("WEM_WEAK_EXCEPTION_MESSAGING")
    public LaunchDarklyClientProvider() {
        String key = getConfigValue(API_KEY_CONFIG);
        if (StringUtils.isNullOrEmpty(key)) {
            throw new IllegalStateException(API_KEY_CONFIG + " must be non-null");
        }
        ldClient = new LDClient(key);
    }

    @Override
    public LDClient get() {
        return ldClient;
    }

    @Override
    public String toString() {
        return ReflectionToStringBuilder.toString(this);
    }
}

public class FeatureFlipLaunchDarklyProvider implements Provider<FeatureFlip> {

    private final FeatureFlip featureFlip;

    @Inject
    public FeatureFlipLaunchDarklyProvider(LDClient ldClient) {
        featureFlip = new FeatureFlipLaunchDarkly(ldClient);
    }

    public FeatureFlip get() {
        return featureFlip;
    }

    @Override

        return ReflectionToStringBuilder.toString(this);
    }
}

public class FeatureFlipLaunchDarkly implements FeatureFlip {

    public static final LDUser ANONYMOUS = new LDUser.Builder("anonymous").anonymous(true).build();

    private static final Logger LOG = LoggerFactory.getLogger(FeatureFlipLaunchDarkly.class);

    private final LDClient client;

    @SuppressFBWarnings("WEM_WEAK_EXCEPTION_MESSAGING")

        }
        this.client = client;
    }

        boolean isEnabled = client.boolVariation(key, ANONYMOUS, false);

Hi @brettcooper,

I've been investigating this issue, and haven't yet been able to reproduce the error you're seeing. The error you're seeing seems to be pretty elusive, and having researched this issue in the past, I believe such errors are fairly isolated to AWS products.

To help with investigation, can you confirm which version of the LaunchDarkly Java SDK you're using? From your partial stack trace, I noticed that you may be using an older version of the client. We have updated the dependency which is producing these errors since then (EventSource), so it upgrading may be worth a try.

Also, does it look like the lambda executions that generate this error have been producing your desired results (no uncaught exceptions, boolVariation returns the correct value)? If that's not the case, we'd be able to update the client to at least handle these errors gracefully.

Hi @atrakh,

We are using launchdarkly-client 2.5.1. It does look like there is a newer version of the client (2.6.0) that we can upgrade to. I upgraded us to the latest client and this error is still happening. Yes, it does appear that the lamdba is producing our desired results despite this error happening.

Also, here is an updated stack trace with DEBUG enabled for Launch Darkly:

Thanks,

@brettcooper have you managed to get around this issue? I am getting very similar error with RabbitMQ client on AWS lambda...

[brettcooper]

@pmalon No, we are still having this issue.

[bwoskow-ld]

Hi @brettcooper,

Can you distinguish if the error happens while the Lambda is executing or upon terminating? I'm curious if LDClient has failed operations during normal execution or if it is something specific to operating the connections while simultaneously being shut down.

[khozzy]

I'm getting the same error but when connecting to MongoDb on AWS Lambda function...

Closing this as the reporter hasn't responded in a year and, per the last comment, the issue doesn't seem to be specific to this SDK.
