Has anybody else seen this? Every so often I notice my phone being REALLY unresponsive and the CPU is pegged. I open terminal emulator and run top, and I see a root-owned process of /system/bin/sh taking up 90% of the CPU. I have to use kill -9 to end it, and the system comes back to life again. Not sure if it's something I did or something that came with the rom. Anybody else seem it before?
