dhcpcd-discuss

Hello,
I have dhcpcd 8.0.3 (a bit old, I know) on an embedded device.
Today I noticed that my resolv.conf is sometimes blank, even if my DHCP
server always provides a DNS value (confirmed through wireshark).

I have tried to fix it with a command dhcpcd -n eth0, this works but then I
found that when I repeat the command call I get periodically correct and
blank resolv.conf. Is that even possible?

best regards
Jan
