Hey Philip,
Thank you for the response. We think we've isolated an eBPF program
we're running which might cause this interaction, I'll see on Monday if
I can get you some more information to help debug.
> 1) Can you please run the command:
apport-collect 2089318
Will aim to get you this on Monday when the team resumes investigation.
> 2) Is there anything I can do increase the likelihood of reproducing
this?
I'll see if I can get you a better shape of the data here on Monday as
well which could help with repro.
> 3) The bug title states you hit this on kernel version
5.15.0-1072-aws. Did you hit this on previous kernels, or is this a new
regression that has appeared in the 5.15.0-1072-aws kernel?
We were definitely able to reproduce this as well on 5.15.0-1070-aws,
and we think this has been a latent bug for a while which a recent
deploy may have exposed.
> 4) You state that the same issue occurs on Azure, and GCP. Is that
using the AWS kernel, or the Azure and GCP kernels (respectively)?
These are using cloud kernels respectively. Those are:
Azure - 5.15.0-1075-azure
GCP - 5.15.0-1071-gcp
Thanks again for taking a look - will aim to share more info on Monday.
Happy Thanksgiving!
