If the Management Server is subject to high demand, the default maximum JVM memory allocation can be insufficient. To increase the memory:
|
||
</div><div class="orderedlist"><ol><li class="listitem"><div class="para">
|
||
Edit the Tomcat configuration file:
|
||
</div><pre class="programlisting">/etc/cloud/management/tomcat6.conf</pre></li><li class="listitem"><div class="para">
|
||
Change the command-line parameter -XmxNNNm to a higher value of N.
|
||
</div><div class="para">
|
||
For example, if the current value is -Xmx128m, change it to -Xmx1024m or higher.
|
||
</div></li><li class="listitem"><div class="para">
|
||
To put the new setting into effect, restart the Management Server.
|

</div><pre class="programlisting"># service cloud-management restart</pre></li></ol></div><div class="para">
