Well as my personal time is worth nearly nothing I'm willing to try a 
bunch of stuff to get this back, so any and all suggestions you have 
I'll be willing to try.

I'm pretty sure we have a recent version of xfs_repair because the tech 
guy at consensys sent me a xfs_repair update, and then he modified that 
version so that it would skip an Assertion error that was causing 
xfs_repair to stop.

from /proc/meminfo:

          total:                used:        free:           shared:    
buffers:     cached:
Mem:  3962441728  919121920  3043319808   0    63930368    361832448
Swap: 2138537984        0 2138537984

MemFree:       2971992 kB
...
SwapTotal:     2088416 kB
SwapFree:      2088416 kB

It seems like this should be enough memory if everything is running 
okay, right?

Is there a way I can find this out and reply back to you?

Thanks so much for all your help, I'll take any and all advice at this 
point.
