To ensure system stability, please follow the specific synchronization steps below. Do not use the "Select ALL" function for large databases. 


 o Symptom

 During performance testing, the synchronization function failed when attempting to sync the entire user database (approximately 120,000+ personnel) at once. 

 Internal analysis confirms that the current system architecture (v1.8.6.x) does not support a bulk sync of 116,116+ users simultaneously. 




ㅇ Steps for Synchronization 

  1. Set Users per Page 

    • Instead of clicking "ALL," set the display limit to a maximum of 10,000 users per page.

  2. Use "Per Page" Menu 

    • As shown on Page 22 of the manual, the sync must be performed using the "per page" menu.

  3. Sequential Sync 

    • Select the users on the current page and click "Sync" first before moving to the next set.

you select max 10,000 users per page and need to click "sync" first



ㅇ Key Takeaway 

In the meantime, please avoid the "Select ALL" button. Syncing in batches of 10,000 per page is the recommended stable method.
