This section describes how you can change the memory settings of the Silk Central servers when out-of-memory errors occur.
The Java heap size of the Silk Central front-end and application servers is set by default to 512 MB (2048 MB for 64-bit front-end server). If you are experiencing out-of-memory errors, for example while copying a project in Silk Central, try to increase the heap size on the front-end or application server.
The following error is an indicator that the Java heap size is to small: java.lang.RuntimeException: java.lang.OutOfMemoryError: Java heap space. This error is reported in the logfile of the front-end server or the application server. Another indicator is the error message The system is now working close to capacity. For security reasons no more users will be permitted to login, which displays when you try to login to Silk Central.
