Severity: 3-Major


With large configuration load, the time it takes to load the configuration might take minutes.


Long loading times. Merged uses a lot of CPU cycles. Using the tmctl command 'tmctl -f /var/tmstat/istats' shows .icomplete and .irequest tables have a large number of rows in them, resulting in merged spending a lot of time merging these rows.


Loading Route Domain and Partition pages in the TMUI.


Restart mcpd using the following command: bigstart restart mcpd. Warning! Restarting mcpd causes the system to reinitialize all processes, which affects traffic. This workaround should be used with caution.

Fix Information

mcpd and merged now provide improved handling of loading large pages so performance issues when loading Route Domain and Partition pages in the TMUI no longer occur.
