</question>
<answer>
<para>
This error is caused when you have exhausted the number of
available file descriptors on your system. The file table in
memory is full.
</para>
<para>The solution:</para>
<para>
Manually adjust the <varname>kern.maxfiles</varname> kernel limit
setting.
</para>
<screen>&prompt.root; <userinput>sysctl -w kern.maxfiles=n</userinput></screen>
<para>Adjust <varname>n</varname> according to your system needs.
Each open file, socket, or fifo uses one file descriptor.
A large-scale server may easily require tens of thousands of
file descriptors (10,000+), depending on the kind and number
of services running concurrently.</para>
<para>The number of default file descriptors set in the kernel is
dictated by the</para>
<programlisting>maxusers 32</programlisting>
<para><varname>maxusers</varname> line in your kernel
config file. Increasing this will proportionally increase
<varname>kern.maxfiles</varname>.
</para>
<para>You can see what <varname>kern.maxfiles</varname> is
currently set to by:
</para>
<screen>&prompt.root; <userinput>sysctl kern.maxfiles</userinput>
kern.maxfiles: 1064</screen>
