Out of memory errors and ISA 4.1

When using IBM® Support Assistant (ISA) 4.1, the Health Center might run out of memory while processing large files.

Processing large files using the Health Center might fail sometimes with the java.lang.OutOfMemoryError message. This can be due to an insufficient Java™ heap size. By default, IBM Support Assistant 4.1 has a maximum Java heap size of 256 MB. You should run the Health Center with a heap size of at least 512 MB.

To set the maximum Java heap size for ISA, add a property value to the rcpinstall.properties file in the ISA workspace. Add or update the value for the vmarg.Xmx property. For example, to set a maximum heap size of 512 MB, add the line:
vmarg.Xmx=-Xmx512m
You must restart ISA for the changes to take effect.
On Windows®, you normally find the rcpinstall.properties file in:
<home drive>\<home path>\IBM\ISAv41\.config\rcpinstall.properties
for example:
C:\Documents and Settings\Administrator\IBM\ISAv41\.config\rcpinstall.properties
On Linux®, you normally find the rcpinstall.properties file in:
<home>/ibm/isa41/.config/rcpinstall.properties
