Of course it's a wraparound. I was not able to reproduce this condition on newer -STABLE. It takes some weeks of uptime and heavy use to reach this stage, unless you happen to know how to increment the counter with a test program (I don't know how). Shouldn't such counters be at least 64 bit wide? -Farid. -- Farid Hajji. http://www.farid-hajji.net/address.html
