The most common cause of this problem is an out of memory error caused by limited heap space in the Java Virtual Machine on the JBoss server instance running caIntegrator. If a study deployment fails due to this error, caIntegrator does not notify the user explicitly and instead logs the error in the server.log file located at the following path:

_\[MATKC:installation root\]\caintegrator2\jboss-4.0.5.GA\server\default\log_

Note that the study's status will continue to show as 'Processing' on the 'Manage Studies' page even after the deployment has failed and the error has been logged.

Studies may show a Status error indicating a timeout after 48 hours when in fact the study is still properly deploying, As a result, a study showing a timeout error should not be deleted or edited. In such a case, the server log correctly indicates that no error or failure has occurred.

In Windows, the heap size is set in the 'run.bat' file located at the following path:

_\[MATKC:installation root\]\caintegrator2\jboss-4.0.5.GA\bin_

In Linux, the heap size is set in the 'run.conf' file located at the following path:

_\[MATKC:installation root\]/caintegrator2/jboss-4.0.5.GA/bin_
