Hello, i am fairly new to OpenBSD (3 months) but i have managed to build a router thats performing very nice... yesterday i had an issue, i didnt understand, the router had very bad packet loss on some times, the router seems loses its route on interfaces participating to ospfd and generates messages like these: Jan 10 16:08:53 brdr0 ospfd[9897]: send_packet: error sending packet on interface

Thanks in advance mindlessgr
