Interestingly I found raspian has an /etc/asound.conf with this in it : pcm.mmap0 { type mmap_emul; slave { pcm "hw:0,0"; } } pcm.!default { type plug; slave { pcm mmap0; } } If I rename it so its disabled my ever growing cache problem goes away. I'm just left with the random freezes to try and cure. My code is doing a lot of stuff, it is possible something else is blocking from time to time. Tricky for me to find it though as running the processes with strace slows it enough to change its behaviour. I have some other real time code, all uses < 20% of CPU with a real time priority yet that also shows small random freezes, my guess is the kernel itself has a Pi specific problem ?
