Hi, I think the tcp connections remain in ESTABLISHED for a long time, it can depend from satellite link (high delay) or a problem with TCP timing in 6.1. (The hardware configurations is the same of 4.x box?)
First of all you can try to set: sysctl net.inet.tcp.inflight.enable=0 and then: sysctl net.isr.direct=0 sysctl net.inet.tcp.slowstart_flightsize=4 or more Can you upgrade FreeBSD? Can you run a "systat -vm 1" and "top"? If you run netstat -in no errors are report? If there are a lot of connections a lot of nmbclusters are used, you can run "netstat -na | grep ESTAB | wc -l". The number of nmbcluster used is related with the number of connections. Let me know.
