debug logs? upstream report?
Comment by Lev Cohan (lev) - Saturday, 04 October 2014, 12:07 GMT
Sorry for the late response but the bug needs about two days to emerge and I don't know any way to speed it up.
Two days ago I restarted systemd-networkd with
File: /etc/systemd/system/systemd-networkd.service.d/debug.conf
[Service]
Environment=SYSTEMD_LOG_LEVEL=debug

The log is added to this comment. I only edited the addresses for reasons of secrecy.

So there's an FD leak on dhcp renewal... please report this upstream.
