Goal

To monitor the size of the Appliance Kit Daemon ( AKD ) using Analytics datasets and Threshold Alerts.

 

This can be useful if you have been effected by 'Bug 16187433 - datasets with lots of breakdowns causes memory fragmentation in akd', 'Bug 22331668 - update dataspan propagation to not include all data - elide some breakdowns'.
Please see the document linked below for more details on how to confirm if you have been effected by 'Excessive kernel virtual memory (exceeding the 32-bit VM limit)' or 'Excessive amount of AKD process (memory) heap fragmentation'.


Sun Storage 7000 Unified Storage System: How to Troubleshoot Unresponsive Administrative Interface (BUI/CLI hang) (Doc ID 1401282.1)

Please note: 'Bug 16187433 - datasets with lots of breakdowns causes memory fragmentation in akd' is  fixed in 2011.1.9.0 and 2013.1.1.5 code.

We have another known issue - Bug 22331668 - update dataspan propagation to not include all data - elide some breakdowns. This is effecting current code so its still recommended to reduce the amount of analytics drilldowns.
