This is the result of ulimit command on my machine: 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) 1024 pipe size (512 bytes, -p) 8 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 1014 virtual memory (kbytes, -v) unlimited
It looks like either pipe size or stack size may be too low. But my main script must be running all the time to collect data so how much should I increase these values to allow infinite executions of external process? -- http://mail.python.org/mailman/listinfo/python-list
