In Materials Studio 8.0 running on a Linux cluster we were trying to change the setting for cpuspercore.  The following are the steps we took to do that.

1.      Login as the user who owns the relevant Materials Studio gateway) installation (This must NOT be root).
2.      Cd to etc/Gateway of the relevant installation.
3.      Run ./gwstop
4.      Run ./config/configure gateway cpucorestotal=24
6.      Run ./gwstart

Now we're getting the following error when trying to restart the gateway.  Any idea why this is happening?  Any help would be greatly appreciated.

Thanks,
Dan
