Hmm, yes. Could very well be. Will get the device to hang and try to ssh into it next time it happens. Also, have Maep installed so will try to remove it and see if that helps at all. Thanks for the pointer.

I have also noticed that the phone doesn't become completely unresponsive but becomes very (and I mean taking about 10 seconds to respond) slow , which does seem to suggest that some process is hogging the CPU.
