    Hi @VictorKalevich,
    What messaging API are you using? I'm wondering if there is a timeout due to inactivity if the app is goes into the background or something like that.

    @Aaron, I think this might be the timeout situation that you ran into previously?

    @VictorKalevich - you might also check out this tip that @trishm shared and see if it fixes your issue.

    Unfortunately no. this is a common request that works in an unexpected way. the "interrupted request" error is sometimes triggered on other requests and looks like the inability of the library to work asynchronously, for example, if you make the same request twice, this error appears on other requests from time to time. the app is always active during these errors. is there any information I can provide you?

    @marc what do u mean saying "What messaging API are you using?"

    Hey @VictorKalevich, I got the answer from your post above. Since Solace supports our enterprise solace APIs (CCSMP, JCSMP, etc.), MQTT, AMQP & REST I wanted to know which you were using.

    Looks like JCSMP 10.9.1 which is the Solace Java messaging api.
    @VictorKalevich can you maybe share some of the code where you connect/send the requests?

    @Aaron looping you in as you might have an idea here.
