High CPU on Archestra Historian storage

Hi All,

Archestra Historian storage is consuming high CPU, due this my overall CPU usage is going up to 100%

Please anyone have any idea on this why it is consuming that much CPU and also let me know if there is any way to resolve this issue.


  • Hard to say without more information. Recognize that even though it is called "Storage", it is also responsible for reading the raw data from history blocks. Also, depending your system, there may be multiple instances of this process running, each servicing different aspects of the system. If you switch to the "Details" tab of Task Manager and add the "Command Line" column, it will be named "aahStorage.exe" and it is possible to distinguish between these multiple instances.
