Periodically I obtain the following error: Assertion `uv__has_active_reqs(req->loop)' failed. can some one help me? many thanks

Hard to tell where the issue has its root-cause, we need to try to reproduce it. Can you provide your node-red flow? Is this the flow recovering itself or do you need to restart the flow or node-red to get to run again? Best regards!

Assertion `uv__has_active_reqs(req->loop)' failed. In the event log of Linux? Or somewhere else? Can you send a screenshot from this error? The DIs are not triggered in 7.5Hz in the flow. It is even not possible to set a frequency for them, they are event based. Are you using the Sink/Source Input Shield? The only thing which is triggered in 7.5Hz is the switch node. Best regards!

I need to setup a test environment to reproduce the issue, can start on Monday (don't have I/Os at the moment). Two questions: Which IOT2050 are you using? Basic or Advanced and which FS does the device have? Are you using the Sink/Source Input Module? Best regards!

I also reduced the flow to have only the DIs - so seems those nodes are responsible for the error. I created an issue on github, R&D will have a look at it. Best regards!
