The main result is veeeeeeeeeeeeeeeeeeeery big syslog and I went short of disk....

Rather curious apport tells that dnsmask is not installed...

Something (presumably network manager) is actually killing dnsmasq:

May 26 20:10:33 internity dnsmasq[28871]: sortie sur réception du signal SIGTERM

I'm retargetting this bug at network manager in the hopes its maintainers might know offhand what might be happening.

[Thomas Hood (jdthood)]

PArnal: The "dnsmasq" package is not installed but the "dnsmasq-base" package is installed. The latter contains the executable which is controlled by NM.

[Thomas Hood (jdthood)]

Same as #1004775?

[Elbarbudo (patricearnal)]

From what I read about #1004775 this seems to be the same bug : mark it as duplicate.

Thanks

I too experimented random dns resolution failures, but I did not make the relationship with dnsmasq.

Status changed to 'Confirmed' because the bug affects multiple users.
