Netdata crashed during update and eBPF plugin also crashed according to entries in /var/crash

Two entries in my Ubuntu 20.04.1LTS /var/crash folder today. One on Netdata itself apparently when the nightly updates were being run and the other on the eBPF plugin again. I see nothing wrong in Netdatas operation. I’ve attached links to the two crash reports and the Netdata error log.

EDIT: Moderator removed pastebin links due to 404

Thanks @chris.pollock for bringing this up. Pinging @Thiago_Marques_0 since he is the brains :brain: behind our eBPF collector.

Hi @chris.pollock,

Thanks the paste bin I could create all the necessary conditions to crash ebpf.plugin, I made the PR invalid_addr_cleanup: Initialize variables by thiagoftsm · Pull Request #10395 · netdata/netdata · GitHub that is bringing a fix for the reported problem.

Thank you!

Good morning @Thiago_Marques_0, glad I could be of some help. I assume the fix you created will be included in tonight’s nightly update?

Hello @chris.pollock, you are right, we merged the PR few hours ago. I expect that you will have another core dump during the update, but tomorrow you should not have them.

Best regards!
