Subject: Programs die when max_map_count is too large

Hi,


setting max_map_count to a value large enough results in programs dying 
at first try.
This is on 2.6.31.6.

15:59 borg:/proc/sys/vm # echo $[1<<31-1] >max_map_count 
15:59 borg:/proc/sys/vm # cat max_map_count
1073741824
15:59 borg:/proc/sys/vm # echo $[1<<31] >max_map_count 
15:59 borg:/proc/sys/vm # cat max_map_count
Killed


thanks,
Jan
