<para>If your machine is lightly loaded, and you are simply
running a very large number of processes, you can adjust
this with the <varname>kern.maxproc</varname> sysctl. If
these processes are being run by a single user, you will
this with the <varname>kern.maxproc</varname> tunable. If
this tunable needs adjustion it needs to be defined in
in <filename>/boot/loader.conf</filename>. The tunable
will not get adjusted untill the system is rebooted. For
more information about tuning tunables, you should see the
&man.loader.conf.5; and &man.sysctl.conf.5; manual pages.
If these processes are being run by a single user, you will
also need to adjust <varname>kern.maxprocperuid</varname>
to be one less than your new
<varname>kern.maxproc</varname> value. (It must be at
least one less because one system program, &man.init.8;,
must always be running.)</para>
<para>To make a sysctl permanent across reboots, set this in
<filename>/etc/sysctl.conf</filename> in recent versions
of FreeBSD, or <filename>/etc/rc.local</filename> in older
versions.</para>
<para>To make a sysctl change permanent place the proper value
in <filename>/etc/sysctl.conf</filename>. More information
about system tuning with &man.sysctl.8; can be found at

with sysctl</ulink> section of the Handbook.</para>
