too many I/O wait events
I updated my APU Board to pfSense 2.5.1.
On the start page i have a box showing the openVPN connections. I use two openVPN servers. On both there are connected clients. VPN is working, but on the second server the clients are not listed. The log (openVPN) says "Error: poll: too many I/O wait events".
What could be the reason?
