The only commonality is that The machines in question are all running bgpd and zebra with a full view in the kernel. The bursts would happen once every 10min. But I am not aware of any timers that would run at that long an interval. I think I will ask over on the zebra list to see if this interval rings a bell with anyone. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
