KB 2150 - Failed to add cache pattern

User gets the following error code while trying to add a cache pattern to a cluster.

This is an internal error and implies that the cache settings page is out of sync with the UI. Please try refreshing the UI page and try the operation again. This problem can also appear if there are some special characters in the cache pattern that are incompatible with iDB or if the cache pattern size is greater than 8192 bytes. 

If it's a sqlite database lock issue, it would imply that some other API or service is holding a lock on the configuration database. In that case you can wait for a few seconds for the lock to be released, refresh the page and try the operation again. Alternatively, if the problem persists, you can go to Settings and then System Settings page and click on the 'Reset Configuration Lock' button.

If the problem persists please contact ScaleArc customer support at scalearc-support@devgraph.com.
