Possible Problem Solution
The large, multinode
BLSR requires more
memory for the
graphical user interface
(GUI) environment
variables.
Reset the system or user CTC_HEAP environment variable to increase the
memory limits.
See the “Reset the CTC_HEAP Environment Variable for Windows”
procedure on page 1-53 or the “Reset the CTC_HEAP Environment Variable
for Solaris” procedure on page 1-53 to enable the CTC_HEAP variable
change.
Note This problem typically affects large networks where additional
memory is required to manage large numbers of nodes and circuits.
