Hello Romeu.
1) Did configured a storage path too?
Cleaning the blob folder on each reboot is pretty fine. Orphaned files
in that directory should only exist if the daemon is not shutdown
properly or unexpectedly. Is that the case? Do you turn off the device
without shutting the daemon down?
2) I can not tell you why the virtual memory increases. The dtnd is
memleak checked via valgrind, which reports no leaks. Moreover, the
software has been tested on platforms with only 32 MB of RAM and even
there, the dtnd is working properly. Thus I am not sure, if the amount
of assigned virtual memory is really an issue. Do you have any reasons
why you are consider that as an issue?
Kind regards,
Johannes
