Using tools such as lsof or truss, if you have them installed.
Code:
truss -rall -wall -p PID
Examine the calls, perhaps some file is missing and program runs continuously in loops or similar issues (could explain the large %sys usage)
Also issue a find to perhaps to locate from which script is that spawned as rbatte suggested.
Something in the line of :
Code:
find /sbin/init.d -type f -exec egrep "svhptdaemon|svhpt" {} /dev/null \;
If you get a match, examine that script for possibility to disable that and what that is actually.
Perhaps i can offer more assistance in couple of days when i get to hpux box.
