Running 0.12.0 binary I get a stack overflow after a few seconds of runtime. Tested on Fedora 35 and vanilla Ubuntu 20.04

Can you share a network dump with DNS packets ?
I suspect this crash is caused by a badly decoded packet, but so far I don't succeed to reproduce in my side .

hello, thank you, shared by email for relative confidentiality of data.

[dmachard]

Can you try this new beta release https://github.com/dmachard/go-dnscollector/releases/tag/v0.12.0-b2 ?

[RonV666]

so far so good, running for about 10 hours so far

[dmachard]
