Jim, Swap spaced used (according to top) is a mere 120k (with 2GB free). How can I check for Swap Wait mode? According to the ps man page, the W process state code is "not valid since the 2.6.xx kernel". Is there some other way to tell? I'm not getting any SW and I assume that with the mere 120k of swap space being used, I won't get much. As I said, this is a machine with 1GB of RAM and other than capturing, I use it for mencoder, a firewall/proxy using iptables, and a file server. And since I'm running these tests without mencoder running concurrently and still seeing the problem, I'm fairly certain it's not a memory/swap issue.
