Hi Robert, Thanks for the reply - I just double-checked, and it is compiled for AMD64. I just tried an i386 binary for kicks, but that does the same thing, and also generates a message about an unimplemented IA32 syscall.
If I run gdb on the head node, it works fine, and nothing seems amiss... running it on the nodes with the problematic install (kernel?), it immediately hangs after the "Cannot find new threads" error. Additionally, I just set up a directory, on the head node, with the entire filesystem from the compute nodes, and chrooted to it, copying the /proc/cpuinfo + meminfo + stat entries into where they should be, and gmond starts up fine in the chrooted environment... essentially what it 'should' be like on the cluster. I'm going to play with it more tomorrow - it's most likely a stupid error on my part, which some sleep might bring to light. :) Thanks again, - Brian
