XMMS seems to have memory usage problems. It hogs a lot of memory quickly, and if left running about two to three hours, will begin to execute of out of the swap area, making whatever music you're playing sound like garbage and driving the load up on your system. A killall xmms quickly fixes this issue. The latest version in the XMMS CVS tree (0.9.5.1?) fixes this problem. It also adds CDDB support, but I have yet to get that to work.
Do the xmms-0.9.5.1 RPMs in Raw Hide work for you?
I uninstalled my current RPMs and installed the RawHide ones. CDDB still isn't working (in fact, I'm missing some CDDB options config options compared to the CVS build), but it could be that I don't know how I'm supposed to be using it. Have any instructions?
I'll keep XMMS running while I'm at work and post an update tonight.
Assumming fixed with current xmms; please re-open if it persists.
