Hello,

I am an admin for a multiple Linux servers that seem to have different ulimit -m settings. I am trying to set the Max Memory Size to unlimited to all of them for consistency, however I can not figure out how to permanently change this setting. I have checked /etc/security/limits.conf but it doesn't seem to be defined there. Is there another place I should be looking?

Thanks,

Hi porscheman170 and welcome to LQ.

It will be helpful to cite the Linux distribution for these servers, in name of distribution and version and also note whether or not there are different distros on these various servers, so that other members can give you correct advice for your situation.

Sorry, the servers are all running SLES11SP3.

Thanks.

Hi,

Please take a look at this link, and note that a reboot was necessary. They cite to use pam_limits

Obviously set different parameters than that particular question is discussing.

I would suggest, however, that you probably should set limits that are less than "unlimited," especially on a server. You want to be sure that, if a particular process "runs away," it will not starve-out anyone else. Consider what limit would be "appropriate, even generous," but that would block any malfunctioning process that was stuck in some kind of loop and gobbling-up memory. Eventually, Linux should be told to refuse the request.

(Often, the process dies when it runs into this, and this just might be your first indication that the process is malfunctioning!)
