I have set ulimits as follows: core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) 256000 max memory size (kbytes, -m) 256000 open files (-n) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited Physical memory on the system is 512MB, yet when the application runs - despite the limits shown above - linux hands almost all of memory to the application.
