Problem:

When trying to login to SilkCentral Test Manager, why do I see the following error: "The system is now working close to capacity. For security reasons no more users will be permitted to login."?

Resolution:

This error occurs when the Java heap size of the FrontEnd Server is not large enough to service requests.

The following information will also be written to the FrontEnd Server log:

"unexpected exception java.lang.OutOfMemoryError: Java heap space Running low on memory. Login blocked."

To resolve this error you should increase the Java heap size of the FrontEnd Server in the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 2.0\SCCFrontendServer\Parameters\JavaJvmMx

The value of the Java heap size should not exceed the available physical RAM on the FrontEnd Server machine and enough memory should be left available for other necessary processes. For example, if 2GB of RAM is available then it may be possible to increase the Java heap size to a value of 1.5GB (1536 bytes in the registry setting) depending on what other processes are running.

You must restart the FrontEnd Server service for this change to take affect.
