It is fixed in 8.0. Kris can you say anything more about interrupt workload bugs on ULE? On all my 7.0 servers I now am using ULE even on the UP ones as it was said there is slight improvements for UP also but all the machines can get intterupts intensive, lots of high speed transfers using nic interrupts. In this scenario am I better of using 4BSD? Chris
