21.2. Increase Management Server Maximum Memory

If the Management Server is subject to high demand, the default maximum JVM memory allocation can be insufficient. To increase the memory:

Edit the Tomcat configuration file:
```
/etc/cloud/management/tomcat6.conf
```
Change the command-line parameter -XmxNNNm to a higher value of N.
For example, if the current value is -Xmx128m, change it to -Xmx1024m or higher.
To put the new setting into effect, restart the Management Server.
```
# service cloud-management restart
```
