We are planning to release 1.21.2 this week.

@tuxianerDE Wohoo! Thank you for testing it. I will try to get it cleaned up and merged in for the next patch release.

Since the PR has already been merged, do you know when the next release/Debian package will be shipped? We currently need to manually downgrade the package on each newly deployed Debian system.

Would it be possible to withdraw the 1.21.1 package from the Debian Repository in the meantime?

A pr for the marshal issue is up! I am having some community members test it out and hoping to have it merged by the end of the week. I appreciate everyone’s patience while this got sorted out 😃

Happy Holidays 🎉

Dear @MyaLongmire ,

Many thanks for all your efforts, much appreciated. I rolled back to 1.20.4 and it’s working as before (obviously) and I can live with that for the time being. Take your time, enjoy the holiday season and stay healthy.

I’ve just noticed some MIBs don’t seem to be getting processed correctly.

Should I raise a separate issue?

mabnz on Dec 18, 2021

@MyaLongmire, the PR also fixes the issue for me. Thanks for your help!

mabnz on Dec 18, 2021

@MyaLongmire had the same issue. I can confirm installing the draft PR removes the panic and I see data flowing in.
