Answer 1

change the ulimit to avoid the error "too many open files" by default max ulimit is 4096 for linux and 1024 for mac, u can change ulimit to 4096 by typing ulimit -n 4096 for beyond 4096 you need to modify limits.conf in etc/security folder for linux and set hard limit to 100000 by adding this line "* hard core 100000"
