Hi,
i wrote a simple test-program to stress-test UML.
#!/usr/bin/perl
while (true)
{
push @a, "a";
}
While executing it, i got plenty of thos messages in syslog:
Mar 14 15:59:01 localhost kernel: 12
Mar 14 15:59:01 localhost kernel: map : /proc/mm map failed, err = 12
Mar 14 15:59:02 localhost last message repeated 1321 times
Mar 14 15:59:02 localhost kernel: 12
Mar 14 15:59:02 localhost kernel: map : /proc/mm map failed, err = 12
Mar 14 15:59:02 localhost last message repeated 3216 times
Mar 14 15:59:02 localhost kernel: 12
Mar 14 15:59:02 localhost kernel: map : /proc/mm map failed, err = 12
Mar 14 15:59:02 localhost last message repeated 786 times
Mar 14 15:59:03 localhost kernel: 12
Mar 14 15:59:03 localhost kernel: map : /proc/mm map failed, err = 12
I expected perl to get killed or get an "out of memory"-error, cause the
UML didn't have swap and only 128MB memory.
So are those errors normal?
I'm using 2.6.4-um1 in SKAS-mode running on 2.6.4 host patched with
BlaisorBlades's 2.6.3-skas3 patch.
If i run the script on the host-machine, perl get's killed as expected.
(the new "kill best process"-stuff is not turned on in the host's
kernel-config)
Thx
Sven

Please check the user archives for the last 3 months or google for mm
map failed.
