MEMORY LEAKS IN POLICY CODE OF DB2ACD FOR AUTOBACKUP EVALUATIONS

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
db2pd -memblock  output for db2acd shows small memory leaks for 
db2acd. 
 
Autobackup evaluations happens every two hour interval.  And 
after each evaluations, db2pd detects a leak of 3 allocations 
from LOC 56, and 1 allocation from LOC 410 for file 521867987. 
 
 
 
A single evaluation leaks: 
3 allocations from LOC 56 ; and 1 allocation from LOC 410. 
 
After one evaluation (2hours): 
Memory blocks sorted by size:

After two evaluations (4hours): 
Memory blocks sorted by size:

The problem happens only for autobackup evaluations. It does not 
happen for the other plugins like autoreorg or autorunstats even 
though  it uses the same parser code.
