| |
No idea where to begin tracking this down :-(. After approximately six days of uptime with a 4.12.0 kernel, the DNS resolver simply quits working. All query attempts come back with "no DNS servers can be reached". External hosts can still query the BIND server running on the host with the non-functional resolver.
Restarting "named" has no effect. Rebooting the machine restores functionality. So far, this is completely reproducible.
Everything worked fine with 4.11.0. Going to try a 4.13-rc4 kernel.
