Thanks.

Actually, even when I do reboot, it does not help much. At best, it might let Xolox run for 40 minutes before I get the "out of resources" error message and Xolox closes itself. Do you have any idea which resources it might be referring to ?

I still think there is a different problem than memory leaks. I have let lots of other programs run around the clock, including Bearahre, napster, etc and have never had this problem with any of the others.

So, I don't think it is a system issue, I think it must be something specific to Xolox. Can you learn anything from the rror reports it generates and sends to you ?
