The file size is about 20 Megs. The process is used as a memory server which keeps a lot of key/data pairs in memory, fetches the data and sends back using TCP on request. Ulimit -a: core file size (blocks) unlimited data seg size (kbytes) 22528 file size (blocks) unlimited max memory size (kbytes) 30720 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 179 pipe size (512 bytes) 1 open files 256 virtual memory (kbytes) 30720 >How-To-Repeat: Try creating a huge mmaped file, and access randomly using many processes.
