RLIMIT_MEMLOCK prevents burning CDROM
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I tried to burn two CDROMs. K3B went through all the steps, except the
last ones, starting with actually burning the disk. When afterwards I
tried to mount it, the disk title I assigned showed, but no content,
thus ruining the disks.
On checking the debug file, I found the following:
cdrecord
/usr/bin/wodim: Operation not permitted.
Warning: Cannot raise RLIMIT_MEMLOCK limit.
I googled that term and found that it apparently has something to do
with security, but if the limit is too low I should raise it. To do so
I was told to add these two lines to file /etc/security/limits.conf:
* soft memlock unlimited
* hard memlock unlimited
I looked at that file, but there is no uncommented line in it, nor any
commented line resembling those two.
Running the command "ulimit" however returns "unlimited".
Next I was able successfully to burn a CDROM in a different computer
which has the same K3B configuration as the first one, as far as I could
see. So it is a mystery to me why I could burn on the second computer
but not the first.
I hope someone can explain to me what happened and what I can do about
it. Many thanks.
