[SOLVED] limits.conf issues

funkmuscle · 2011-06-08 20:35:24

Hey, every time I launch Ardour, I get a Cannot lock down memory area (Cannot allocate memory) from Qjackctl and Ardour telling me to run ulimit -l...

well the results from ulimit -l is 64 but /etc/security/limits.conf:

* - rtprio 0
* - nice 0
@audio - rtprio 99
@audio - nice -10
@audio - memlock memlock unlimited

any help?

Are you in audio? Try using @users, or put your username there...

yep:
$ groups
audio optical storage scanner camera users

64 bytes? That small size would explain why ardour is not locking in enough memory. Try running ulimit -l <something_larger>. For example mine is 452192 and I don't think I've ever had to change it.

I've never had this issue in all my years of using Arch..... I'd fix the limits.conf the way it is and I'm set... this is really strange since I've installed a new harddrive.. My old drive died, bought a new one, reinstalled Arch 3 times because it's just not working right... fixed most issues except this one...

what do you mean by
Try running ulimit -l <something_larger>.

I did
$ ulimit -l 400000
bash: ulimit: max locked memory: cannot modify limit: Operation not permitted

ran as root:
# ulimit -l 400000
then:
$ ulimit -l
64

edit:
nevermind,,, fixed...
in /etc/security/limits.conf
I added
@audio - memlock 40000

I think I had it unlimited or something..
Thanx all

"@audio - memlock 40000"

didn t solve it here. strange.....do you use the Liqourix-Kernel?

yeah.. and the RT

capoeira · 2011-07-12 21:58:14

something is broken here

[root@myhost studio]# ulimit -l unlimited
[root@myhost studio]# ulimit -l
unlimited

and Ardour 3 is still complaining

ardour3 alpha9 runs good for me

capoeira · 2011-07-13 19:10:47

it was an incredible conincidence.......

while your problem was caused be a wrong line in limits.conf, mine was caused by the login-manager. I used elsa (beta-software).....now that I changed to slim, the problem is gone

so: solved²
