ECO KIT SUMMARY:
A dupatch-based, Early Release Patch kit exists for HP Tru64 UNIX 5.1B that
contains solutions to the following problem(s):
This ERP kit for 5.1B PK3 contains fixes that address the following two issues:
- A system panic with the panic string 'vm_pg_free: page mapped' can
potentially occur on HP Tru64 UNIX V5.1B systems when bigpages are
enabled. The problem is caused by skewed mapping upon excessive cowfaults.
The panic exhibits the following footprint:
0 panic
1 vm_pg_free
2 u_anon_free
3 u_anon_unmap
4 u_map_delete
5 vm_map_exit
6 exit
- Changing memory protection under certain conditions can result in a
kernel memory fault panic exhibiting the following footprint:
0 panic
1 event_timeout
2 printf
3 panic
4 trap
5 _XentMM
6 _a_lock
7 u_anon_protect
8 u_map_protect
9 mprotect
10 syscall
11 _Xsyscall
Customers with and without bigpages enabled can benefit from this ERP.
The Patch Kit Installation Instructions and the Patch Summary and Release
Notes documents provide patch kit installation and removal instructions
and a summary of each patch. Please read these documents prior to
installing patches on your system.
The patches in this ERP kit will also be available in the next mainstream

system files on your system. The dupatch utility provides the baselining
capability.

other ERP available at this time for this product version.
3) This ERP kit will NOT install over any Customer Specific Patches (CSPs)
which have file intersections with this ERP kit. Contact your normal
