We are continuing to experience some authentication issues with our OpenVPN server. A recent upgrade has introduced a bug that leaks file handles, ultimately leading to system resource starvation. We've filed a bug report, but have yet to hear back from the software maintainers. While we continue to investigate this bug and/or find a workaround, we have implemented a watch mechanism that restarts the VPN server after every 500 connections or stale file handles. Unfortunately, this will cause existing tunnels to be restarted, but the software should automatically reconnect. We will post another update when we know more.
