dhcpcd going away quietly after half a day
Hi, since a 2023-05-30 update to my coworkers' Arch desktop machines, machines have started to go off the network after 12 - 24 hrs. When I check such a machine, dhcpcd is gone without a trace, nothing in the logs. Manually restarting dhcpcd will bring the machine back online, but only for the above timespan. I downgraded dhcpcd from the current 10.0.1 package to 9.4.1, but that doesn't make a difference. Before rolling back two dozen machines to the previous 2023-04-26 installation: Does this ring a bell for anyone?

Does the timeframe somehow correlate with the DHCP lease time in your network? Maybe dhcpcd crashes when trying to renew the lease? Do you have access to DHCP server logs? Or maybe run a (tcpdump/wireshark) port bootps in the background and then check the time of the connection loss.

Got two client installations updated 31.05.2023 and 01.06.2023. One connects to to very old OpenWRT, second to year-old dnsmasq on arch linux. No issues. Regards, Łukasz

No issues.
Thanks. After an off-list-suggestion, I am restarting dhcpcd from a cron.hourly script, until I find more time to investigate (or not...).
