Defensive debug code consumes an extra measure of heap storage
for the lifetime of the process.

Problem conclusion

  • This APAR fix adds the custom property retainProxies
default value of false. Setting to a value of true
enables this added protection along with the expense of added
memory consumption.  This should be enabled only at the
suggestion of IBM support.

The fix for this APAR is targeted for inclusion in fix pack
8.5.5.21 & 9.0.5.11. For more information, see 'Recommended
