Grid Mathematica 7 Idle Kernel Timeout
I just finished upgrading our Grid Mathematica cluster from 6 to 7 today. I've been doing calculations that take about 12 hours per kernel for the last few months, so the switch from 8 to 20 kernels is a welcomed improvement. However, I'm having a problem keeping my slaves connected: there appears to be an idle timeout and it causes the slaves to disconnect. I have all the settings possible for timeout set to 0 (indefinite). The problem is fixed by occasionally printing status information back to the master notebook. Prior to the upgrade, I'd connect the slaves on launch and have them active without disconnect for weeks at a time.
