Suggestion from left field: try running mondoarchive under memusage:

	memusage mondoarchive <all your wonderful options>

or perhaps using operf/opreport instead of memusage. It might even be
better to run operf in system-wide mode to catch everything going on.
See "man operf" for details.

memusage is part of the glibc-utils RPM on Fedora/CentOS/Red Hat.

operf/opreport is part of the oprofile RPM on Fedora/CentOS/Red Hat.
Can't speak about other distros, but they're probably similarly named.
