This script (tcpclient3.pl) create a new chart when it start, this is to demonstrate a way to have multiple client connected to the same CdC instance. The chart is normally closed at the end but not if the script crash. Then if you save configuration when exiting CdC the extra chart are saved and reopened the next time. As the maximum number of chart is 10 it is expected you get this message when the script try to create a new one. Just close every extra chart, save and exit, there is no risk to close the last one.
