--- Comment #1 from Emil Velikov emil.l.velikov@gmail.com --- Just sharing some ideas, I likely won't be able to help much.
Possible issues include: - file is not there, has wrong permissions, is corrupted - map fails due to wrong permissions of the segment, OOM conditions
strace should help narrowing it down.
