Re: [squid-users] squid 3.2.0.16 built --with-filedescriptors=16384 only has 256 file descriptors

Thanks. It turns out the bash shell ulimit is 256, and Apple limits kern.maxfilesperproc to 10240, such that even "max_filedescriptors 16384" in squid.conf could not overwrite that:

# sysctl kern.maxfiles kern.maxfilesperproc
kern.maxfiles: 12288
kern.maxfilesperproc: 10240

I can, however, use sysctlt to overcome that.
