Created attachment 107321 [details] systemd-networkd debug log Since my last systemd upgrade (215 -> 216) networkd is having timeouts when renewing my dhcp lease. This happens every two days. The log output is at every incident the same. Log extract: Oct 02 09:40:51 G550 systemd-networkd[179]: Failed to save lease data /run/systemd/netif/leases/4: Too many open files Oct 02 09:40:51 G550 systemd-networkd[179]: extern0 : Failed to save link data to /run/systemd/netif/links/4: Too many open files Oct 02 09:44:15 G550 systemd[1]: systemd-networkd.service watchdog timeout (limit 1min)! Oct 02 09:44:15 G550 systemd[1]: Unit systemd-networkd.service entered failed state. Oct 02 09:44:15 G550 systemd-networkd[18244]: extern0 : gained carrier config file: [ext0.network] [Match] Name=extern0 [Network] DHCP=yes 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 bug report. I only edited the addresses for reasons of secrecy.
