How do I increase the size of file descriptors on mac

Question

I am getting an error from squid

WARNING! Your cache is running out of filedescriptors

What should i do in my mac to prevent this error?

I think you can use something similar to:

# sysctl -w kern.maxfiles = nr
# sysctl -w kern.maxfileperproc = nr

To make it persistent edit /etc/sysctl.conf like this

kern.maxfiles=nr
kern.maxfileperproc = nr

Later method needs reboot or reload via sysctl.

You may also need to raise the ulimit settings for regular users:

ulimit -S n nr
