How to fix these errors and warnings with Integration Runtime (Self-hosted) Host Service on Windows

Question

Our Windows server administrator found that the Windows event log is so full that it can only hold entries for the last few hours. The following error occurs 3 times in a row in the Event Viewer every couple of hours:

He also reported that there’s a flood of warnings that occur every 5-15 seconds:

Can anyone provide advice on how to fix these issues?

We have not seen any problems with this SHIR executing ADF activities.

Thanks.

Hello Richard Martinez,

Welcome to the Microsoft Q&A forum.

I just checked with my internal team and as per thier suggestions, you can ignore those errors. This error won't impact the pipeline runs.

Possible root cause for this error: System.ComponentModel.Win32Exception (0x80004005): Access is denied

it's mostly possible that there are some third party application running on the node which is blocking the process to exit. You could leverage Process Monitor which also can shows stack trace, from there we can know if some third party module was hooked into SHIR processes.

If you choose to capture a dump, please ensure it was captured at the point where access denied exception was thrown. There are a lot tools which could be configured to capture exception dump.

How to capture the dump:

Also, please check if your SHIR is upto date. If not, please install the latest SHIR version and see if you still see these errors.

I hope this helps. Please let me know if you have any further questions.
