I've been informed that there have been some reports of problems with MySQL connections failing due to randomized ephemeral ports. If you're one of the people affected, could you check a few things and then contact me? Things to check: 1. Are the stuck sockets / failing connections sticking in the SYN_SENT state? 2. Does the range of ports in use look like it's relatively random, or do you see only a small amount of your portrange being used? (The portrange is 1024 to 5000 by default.) 3. Does setting net.inet.ip.portrange.randomized=0 solve the problem for you? Thanks, Mike "Silby" Silbersack
