we have some application server (services) developed in XE7.
slowly, but they use more and more memory.
of course i have debuged the application looking for some memory leaks
with fastmm fulldebug mode. It cannot help, no problem with projects.

i try to use LogMemoryManagerStateToFile , to store the memory status to file.
I have found an interesting line in it. This is a test VCL project with some buttons.

FastMM State Capture:

24K Allocated
1255K Overhead
2% Efficiency

Usage Detail:
5952 bytes: UnicodeString x 136
4352 bytes: Unknown x 92 <<<< THIS ONE
4100 bytes: TButton x 5
1012 bytes: TForm1 x 1

in the application servers this line reports more and more used memory.
Can you tell me what UNKNOWN means? How to find the problem ?

best regards
