Not XM, no.
XM process numbers are rather deterministic as they get created
during bootup of the system. There are 5 processes belonging to
XM (at least on all currently supported releases) and they should
be PINs 10..14 or 11..15.

If you see other processes doing a very high number of disc IOs,
but they do not show a program name, then my guess would be
you are looking at io_mgr_process PINs which probably do
DTC communication event logging, typically due to a hearbeat
problem on your link because SQE-Test is not enabled on some of
your LAN tranceivers on some of your DTCs.
