Memory limit
The memory limit is based on Resident Set Size (RSS) memory by using Linux cgroups feature. You can actually use more than 32MB, but if you go over the limit your programs will be swapped out to disk and everything will run very slow. It's not advised to use 100% of the limit either, for the same reason as you would not run your desktop computer at 100% memory usage. You will get a warning if you use more than 80% of your memory limit when you log in. You can also show your current memory usage with the command showmem
