Re: The function of system main process?

found this on: unhashdaemon
at http://hpwww.epfl.ch/HPUX/security/PHKL_16750

PHKL_15915:
Failure to allocate page directory alias entries causes the application to receive SIGBUS. Any application that makes extensive use of alias pdir entries running on a fast system will use all the available alias pdir entries before the unhashdaemon wakes up. This daemon wakes up once per second and is responsible for allocating more of alias pdir entries are the are all consumed. The kenel uses alias pdir entries when it want to mmap the same offset twice. When the number of available entries falls below the thresholds (min_alias_entries and min_alias_pdirs) the unhashdaemon calls grow_aatables() to allocate more entries. The fix was to call grow_aatables() directly whenever the need arises instead of relying on the unhashdaemon to wakeup at the right time.

I believe that the "str"'s are streams processes.
