Status: Unverified
FACT(s) (Environment):
Progress 9.1C
UNIX
SYMPTOM(s):
Memory mapped procedure library.
Each user allocating their own memory space for the same procedure library.
Glance and/or top utility(s) show each user accessing a memory mapped procedure library.
CAUSE:
Bug# 20020211-015.
CAUSE:
Calls Using MAP_PRIVATE always cause mmap() to create a private copy of the memory map, even when Progress never writes to the memory map.
FIX:
