Thanks. Although having maxfiles == maxfilesperproc might make sense for special cases e.g. a machine completely dedicated to one process -- It is dangerous at best for the general case. Any malicious program can make a machine running FreeBSD non-functional. The default should be set with the average user in mind, namely protecting him from himself. -Kip On Tue, 21 Sep 1999, Gregory Sutter wrote: > On Sun, Sep 19, 1999 at 03:16:40PM -0700, Kip Macy wrote: > > Is kern.maxfiles the total number of files that can be open on the system > > at one time?
