    Hi Jin,

    I was observing the DNS-323 memory (64MB) and CPU usage when importing music and this is what I am seeing:

    - Start MediaTomb in daemon mode - 0% CPU 12% Memory
    - Import Music Manually from Web UI - 80-85% CPU, memory slowly rises to 21%
    - Import Music Finishes - 0% CPU, memory stays at 21%
    - 15 mins later, Import more music manually - 80-85% CPU, memory stays at 21%
    - Import Music Finishes - 0% CPU, memory stays at 21%
    - 1 hour later - memory still at 21%
    - Restart MediaTomb in daemon mode - 0% CPU, 12% Memory

    Should I be concerned about this 9% of memory that is not released after an import?

      I know that we have some queues which do not shrink, it is OK that the memory is going up during import, but I believe it should go down again.

      I'll have to take a look, the valgrind session happens before the release, so who knows :)

      Normally I wouldn't be concerned with less than 6MB of wasted memory, but I only have 64MB in this NAS :)  Let me know if you find anything.

      Thanks.
