Table 2-2 describes the potential cause(s) of the symptom and the solution(s).

Table 2-1 Browser Stalls When Downloading jar File From TCC+

Possible Problem Solution

The large, multi node

BLSR requires more

memory for the 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” section

on page 2-15 or the “Reset the CTC_HEAP Environment Variable for

Solaris” section on page 2-15 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.
