Comment 2 for bug 410841

I am a hobby DJ and have tested Mixxx 1.7.0 thoroughly at home during the last weekends. In particular, I tested Mixxx on my Laptop (Dual Core 2 Duo 1.66GHz, 2 GB DDR2 RAM, two cheap USB sound cards) without MIDI and Vinyl control. Both on Vista (32Bit) and Kubuntu 64 Bit (I used the old portaudio packages as recommended) Mixxx was not able to overcome a time period of 7 hours without crashing once.

I found out that the main memory usage of Mixxx grows continuously whenever new songs are loaded to the decks. After four to five hours of DJing, Mixxx takes about 1.5 GB of memory on my system. A crash is inevitable.

Running the more powerful memory leack checker valgrind yields numerous of definite and possible memory leaks, see attachment.
