Environment
VMware vCenter Server 4.1.x
VMware vCenter Server 5.0.x
Cause
The amount of memory configured for the Tomcat Maximum memory pool can quite often be too low in large vCenter Server environments. If Tomcat runs out of memory, some or all of the VMware VirtualCenter Management Webservices based features might not function correctly, or at all.
Resolution
This issue may occur due to a conservative Java Memory Pool setting. The Tomcat service depends on the Java Memory Pool setting for its various functions.
To resolve this issue, increase the value of memory pool in the Java Memory Pool setting.
To increase the maximum memory pool value:
-
Click Start > All Programs > VMware > VMware Tomcat > Configure Tomcat.
-
Click the Java tab.
-
Double the number in the Initial and Maximum memory pool field.
-
Click OK.
-
Note: It may take a period of time for the increase in the memory pool value to take effect, up to 15 minutes. A further increase of the Maximum memory pool value may be required, until the issue is resolved and no OutOfMemory errors are recorded in the stdout_datestamp.log file, as noted in the Symptoms section.
