See if strace is installed on the system.

When the mxt process appears in ps aux or ps -ef, quickly note the PID
(suppose it's 6789) and attach to the process with strace:

    strace -p 6789

See if that yields anything.  Also, have you perused ALL log files for traces
of mxt ?

Try as root:

    find /var -type f -mtime 0 -exec grep -Hi mxt {} \;

That will scan every regular file under /var.  The -H option to grep has grep
print the filename that mxt was found in.
