Comment 97 for bug 149076

I've corrupted 2 disks with output:

"----------------------

I've set up max locked memory in /etc/security/limits.conf by adding lines:
* hard memlock 512000
* soft memlock 256000
After relogin I've check out limits:

$ ulimit -a
max locked memory (kbytes, -l) 256000

And now the burning process goes fine.
