<p><p>Do you have a crashing Zabbix Server and looking through the log <code>/var/log/zabbix/zabbix_server.log</code> you see the following out of memory message?</p>
<div class="highlight"><pre><span></span><code>__mem_malloc: skipped <span class="m">0</span> asked <span class="m">24</span> skip_min <span class="m">18446744073709551615</span> skip_max <span class="m">0</span>

<span class="o">[</span>file:dbconfig.c,line:94<span class="o">]</span> __zbx_mem_realloc<span class="o">()</span>: please increase CacheSize configuration parameter
</code></pre></div>
<p>Besides the clear solution to the error, that's a common issue on servers that have a few monitoring items on it (servers, switches, firewalls, databases, etc...). To solve, go to your zabbix_server.conf and look for the CacheSize property and set it to a higher value. Its default should be 8M. At a customer that has somewhere between 4 servers, 7 firewalls/appliances, and a few other things, a 32M did the job, but you can set up to 8G.</p>
<p>See ya folks.</p></p>
