Dear list I am in the process of learning to manage ulimits. I feel I must have hit some limits in one of my boxes but as I am googling around most information about ulimits are very very brief. It's explained how to set soft or hard limits but not mentioned what's the current status. e.g. I know from RTFM that ulimit -n can control the maximum number of open file descriptors, but how do I know the exact number of open file descriptors on my system? Also -m control the maximum resident set size, well I yet didn't find a very clear explanation of resident set size, is it what shows up when I use 'free' or 'top'? And there is no 'resident set size' in /proc/meminfo too. Most google results explain ulimits in less then 3 pages but I guess to get enough background knowledge of it I need at least a article much longer than that. Now I am still googling around and would very appreciate if someone can recommend me some good article to read.
