Hello,

This seems pretty low (and normal). Probably there are some problems 
with external libraries (API) using malloc and not properly freeing 
memory. This is not a problem with the library itself, but more with the 
way the library is used. For example the libpcre library had this sort 
of leak when used in the regex modules.

Look for external libraries (by checking the dependency list) for the 
custom setup you have. Then, try to match every external library 
instantiation(allocation) (via library method) to a corresponding 
release of resources.

Cheers
Marius
