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. -------- Original-Nachricht -------- > On Wed, Jun 20, 2012 at 7:30 AM, I wrote: > > I'm running one of the nightly 3.2.0.16.
