Is there a way to use JDB to query sigma0 to see which task owns an address? Say for example I have a virtualization system built using Fiasco L4Re and all I have is the instruction pointer for where a potential problem, possibly a memory leak. Is there a way to use JDB to find out which task the L4Re system thinks owns that address?

With JDB you can inspect all the address spaces and thus also see which areas of the virtual address space is valid in each task. Press 'p' on the task in the 'Q' list. Be prepared that the same virtual addresses in different tasks might have different contents.
