[Openvpn-users] CPU 100% when waiting for ping-restart

[Markku Leinio <markku.leinio@xxxxxxxxxxxxxx>]

openvpn.exe (in the client-side) starts spending 100% CPU time when ping
has failed and it is waiting for ping-restart to happen. Is this a known
fact, and can it be avoided somehow?

CPU load is near zero, but when the network connection fails, my laptop
starts spinning the fans as CPU load goes to 100%, until OpenVPN notices
that the connection has failed.

Server is Linux 2.4.x, client is Windows XP Pro SP2, both running
OpenVPN 2.0.
