My blades have been rebooting every hour to the second since I got them. This suggestion is what worked for me with a few changes. Evidently the blades do not like having the same server IP address listed for primary and secondary. What I did was bind a second IP address to the same NIC on my Linux box running the stratum proxy. Changed the secondary address on the blade to the new secondary IP bound on the stratum proxy and problem gone.
Thanks to bluedragon and gbsray for pointing me in the right direction.
Edit: fixed (I hope) a missing closing quote tag that was messing things up.
