I ran my analysis over 12 hours and found that there are brk()s occurring roughly every 10 minutes and the heap is just increasing in size and never shrinking, indicating a small memory leak. gdb shows: (gdb) where #0 __brk (addr=0x31fa000) at ../ports/sysdeps/unix/sysv/linux/arm/brk.c:28 #1 0xb6298826 in __GI___sbrk (increment=135168) at sbrk.c:53 #2 0xb626209a in __GI___default_morecore (increment=<optimized out>) at morecore.c:47 #3 0xb625f1e2 in sysmalloc (av=0xb62f54e8 <main_arena>, nb=72) at malloc.c:2462 #4 _int_malloc (av=av@entry=0xb62f54e8 <main_arena>, bytes=bytes@entry=64) at malloc.c:3800 #5 0xb6260576 in __GI___libc_malloc (bytes=64) at malloc.c:2891 #6 0xb636d0f4 in operator new(unsigned int) () from /usr/lib/arm-linux-gnueabihf/libstdc++.so.6 #7 0xa92c2b42 in core::dbus::Message::Reader::Reader(std::shared_ptr<core::dbus::Message> const&) () from /usr/lib/arm-linux-gnueabihf/libdbus-cpp.so.4 #8 0xa92c2cc0 in core::dbus::Message::Reader::pop_variant() () from /usr/lib/arm-linux-gnueabihf/libdbus-cpp.so.4 #9 0xa9356a98 in core::dbus::Codec<core::dbus::types::Variant>::decode_argument(core::dbus::Message::Reader&, core::dbus::types::Variant&) () from /usr/lib/arm-linux-gnueabihf/libmedia-hub-client.so.1 #10 0xa9374608 in core::dbus::Result<core::dbus::types::TypedVariant<unsigned long long> >::from_message(std::shared_ptr<core::dbus::Message> const&) () from /usr/lib/arm-linux-gnueabihf/libmedia-hub-client.so.1 #11 0xa937484c in core::dbus::Result<core::dbus::types::TypedVariant<unsigned long long> > core::dbus::Object::invoke_method_synchronously<core::dbus::interface---Type <return> to continue, or q <return> to quit--- s::Properties::Get, core::dbus::types::TypedVariant<unsigned long long>, std::string, std::string>(std::string const&, std::string const&) () from /usr/lib/arm-linux-gnueabihf/libmedia-hub-client.so.1 #12 0xa9374a98 in core::dbus::Property<mpris::Player::Properties::Position>::get() const () from /usr/lib/arm-linux-gnueabihf/libmedia-hub-client.so.1 #13 0xa93c6f66 in AalMediaPlayerService::position() const () from /usr/lib/arm-linux-gnueabihf/qt5/plugins/mediaservice/libaalmediaplayer.so #14 0xaaae6332 in QMediaPlayer::qt_metacall(QMetaObject::Call, int, void**) () from /usr/lib/arm-linux-gnueabihf/libQt5Multimedia.so.5 #15 0xb65ac518 in QMetaProperty::read(QObject const*) const () from /usr/lib/arm-linux-gnueabihf/libQt5Core.so.5 #16 0xaaaba3e2 in ??
