Symptoms

Client receives error:

java.lang.OutOfMemoryError

in their java plugin log. 

There are two ways to get this log: 

1)  In the bottom, right hand part of the machine you will see a Java coffee cup icon.  Right click on it > Open Console.  Note that if there are more than one icon then look for the log that references Demantra in the URL

To make sure you are not including old messages, press the Clear button and then try to recreate the issue again.

2)  If the machine has frozen up then a log is still usually saved on the back end of the machine.  This can usually be found by going to C:/Documents and Settings/<Username>/Application Data/Sun/Java/Deployment/log

Note that this can happen in different scenarios such as, but not limited to, running a Demantra worksheet or exporting the contents to Excel
