The core file size is 0 by default, which results in no core being generated:<br />
<pre><br />
sh# ulimit -a<br />
core file size (blocks, -c) 0<br />
...<br />
...<br />
...<br />
</pre><br />
<br />
Set it to unlimited:<br />
<pre><br />
sh# ulimit -c unlimited<br />
sh# ulimit -a<br />
core file size (blocks, -c) unlimited<br />
...<br />
...<br />
...<br />
</pre><br />
<br />
Ensure that the core is written to a writeable area of the system, such as <code>/tmp</code>, by modifying the value of <code>/proc/sys/kernel/core_pattern</code>:<br />
<pre><br />
echo "/tmp/core.%e.%p.%h.%t" > /proc/sys/kernel/core_pattern<br />
</pre><br />
<code>%e</code> program name<br /><br />
<code>%p</code> pid<br /><br />
<code>%h</code> hostname<br /><br />
<code>%t</code> timestamp</div>Milosivanovic
