shelf view (multishelf mode) to network view on any nodes, from any workstation. This is accompanied by
an Exception occurred during event dispatching: java.lang.OutOfMemoryError in the java window.
Possible Cause The large, multinode BLSR requires more memory for the graphical user interface (GUI)
environment variables.
Solution Set the system or user CTC_HEAP environment variable to increase the memory limits. Complete
the Set the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP Environment Variables for Windows, on page
49 or the Set the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP Environment Variables for Solaris, on
page 50 to enable the CTC_HEAP variable change.
This problem typically affects large networks where additional memory is required to manage large numbers
of nodes and circuits.
Note
Set the CTC_HEAP and CTC_MAX_PERM_SIZE_HEAP Environment Variables for Windows
Before proceeding with the following steps, ensure that your system has a minimum of 4 GB of RAM. If your
system does not have a minimum of 4 GB of RAM, contact the Cisco Technical Assistance Center (TAC).
