Hi all,
I'm not sure if I have made a mistake, but I cannot seem to set the ulimit memlock for users on the MICs.
Firstly, I am running the MPSS release 3.2.3 with the firmware upgrades that come with it, on RHEL 6.3.
If I login to a MIC, I can see the ulimit settings by issuing: ulimit -a
The max locked memory by default is 64. I can set this, as root, to unlimited by issuing: ulimit -l unlimited. Then, if I logout the change is lost.
So, I looked for the ulimits.conf file. I extracted the base file: /usr/share/mpss/boot/initramfs-2.6.38+mpss3.2.3-knightscorner.cpio.gz to a new location using zcat and cpio. I then noticed two files. In the base directory there are:
/etc/security/limits.conf
/etc/security/limits.d/95-memlock.conf
The file limits.conf contains only examples. However, the 95-memlock.conf file contains:
* - memlock unlimited
I have tried different permutations, but none, as of yet, seem to work.
I created a new file: /var/mpss/common/etc/security/limits.conf that contains:
* - memlock unlimited
but that seems to be ignored.
I did notice the following post regarding a similar problem, but the software architecture of the MICs appears to have changed and this is no longer valid:

I acknowledge that I may have made a trivial mistake :)
Any help and/or examples is much appreciated.
Cheers,
Gerald
