Hi,
I think I'v heard this before - there is some weird memory usage
behavior with the Solaris-Sparc-SMP-CC version of Charm++
built upon net-sol-smp version of Charm++.
You may try the latest version of NAMD, but you have to build every thing
from source out of the CVS - Charm++ and NAMD (they have separate CVS
servers).
