Well, that was an interesting experiment! It is, indeed, hitting the "return" at that point. In fact, many more times than the counters showed by "vmstat -i" indicate. Even when I'm not noticing any problems, the return counter I installed climbs faster than the number of interrupts shown for the ioapic pin, but over the course of a couple of back-to-back, longish hangs, the vmstat counter increased by about a half million, but my return counter jumped by about 23 million! -tih -- Popularity is the hallmark of mediocrity. --Niles Crane, "Frasier"
