Memory Leak in AMD64 and RPi builds

Ok,
Thanks.
Under services reporter it says all Thumbnails are built (100%). I did set it up as you suggested anyway - thank you.
BTW
Not sure if its related but I found something funny - when the spectrum analyser runs in the small window in the tool bar (that says the name of the file, time etc) it causes the Pi to use about 25% of its CPU when playing music - if I turn it off the CPU usage drops to around 5% when playing music...
Not sure if its related. I play mostly FLAcs and have a very modest EQ

Bob, just a wild thought, but someone reported a memory leak over on ARM as well this morning on raspbian. Do you think the two might be connected? I speculated in that thread that it might be related to the thumbnailing memory leak on ARM (which is improved but not fixed). Do you think the leak in this thread could be connected to thumbnailing? My amd64 instance where I see no memory leak already has all of its thumbnails built so that's one differential. That would also explain why you might see it on newer installs, but not longstanding ones.
Anybody else running the 64 bit version on Arch? Anyone seeing the memory leak?

I was wondering about that when I saw the message about the memory leak on arm.
I would think that with a small library though I wouldn't see a leak, at least not a massive one.

You could turn the analyzer off to see if that's using memory. It does actually consume a fair amount of CPU on a Pi to display that.

It seems there is a memory leak associated with playback not much with Thumbnailing as far as I can see.
I wiped my thumbnails and generated new ones for 6k tracks and used up a total of 8 megs so if there is a leak there, it's not huge.
I did leave an mp3 playlist on a test machine over the weekend and it was up to 1.8g of memory used by the time I came in today.
Testing MC20 to see if it's been there forever or if it's new.

Could you just try looping a mp3 file for local playback? I got a big leak leaving a machine running over the weekend. It might be something about my audio settings too or a leaky audio driver perhaps...
