I am having trouble getting rid of the CStack limit when running my code. I managed to get rid of the error by appending
* hard stack unlimited
* soft stack unlimited
* soft memlock unlimited
* hard memlock unlimited
root soft stack unlimited
root hard stack unlimited
root soft memlock unlimited
root hard memlock unlimited
to /etc/security/limits.conf which fixes the problem on RStudio Desktop.
I get the following output from running Cstack_info()
> Cstack_info()
size current direction eval_depth
NA NA 1 2
This is the output from ulimit -s on the desktop terminal
coolshades@coolshades-ws:~$ ulimit -s
unlimited
Code runs perfectly on RStudio Desktop.
On the same machine, I also am running RStudio Server (free) to run code remotely. It would seem that these settings are not sticking when running RStudio Server.
This is the output from Cstack_info() on the RStudio Server
> Cstack_info()
size current direction eval_depth
7969177 26336 1 2
This is the ulimit output from terminal on the RStudio Server
coolshades@coolshades-ws:~$ ulimit -s
8192
I am able to change the limit back to unlimited with ulimit -s unlimited. But it will only kick in after Rsession is restarted. However, when I restart the R session, the output of ulimit -s reverts back to 8192.
I am out of ideas as to how best to tackle this problem and hope a more experienced RStudio Server user will be able to advise on this matter.
I have solved this problem.
I had to make the following changes to the following files:
sudo nano /etc/systemd/user.conf add DefaultLimitSTACK=134217728
sudo nano /etc/systemd/system.conf add DefaultLimitSTACK=134217728
Make sure the number you define is a power of 2, else Ubuntu fails to login for some reason.
I have 128GB of RAM. So I have set my limit to 2^27.
Hope this helps someone with the same problem.
