Adjusting the Java Heap Size All All


The following error message appears in the service status section of the GlobalScan panel and in the uptime.log file:

IOException: Not enough space

This error indicates that there is not enough Java heap space (a repository for Java objects and free memory) on the monitoring station. The error message does not indicate that there is insufficient disk space on the server.


To resolve this problem, increase the Java heap size on the monitoring station. For more information, please see Adjusting the Java Heap Size.

The amount that you will need to increase the heap size will depend on your deployment and system capabilities. You may need to experiment to find the optimum setting or contact uptime Support for further assistance.
