Make sure you set ulimit -n before starting Riak. A value of 1024 or larger is recommended (on OS/X the default is 256). Example:
$ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited file size (blocks, -f) unlimited max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 256 pipe size (512 bytes, -p) 1 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 266 virtual memory (kbytes, -v) unlimited $ ulimit -n 1024 This is a common cause of timeouts and connection failures on OS/X.
