I am getting file system utilization threshold breached but currently no active alarms able to see. In below output at two places can see high disk utilization. Can someone tell me if this is an issue and how we can reduce it asap ?

We have found that cache was full after checking show statistics dre detail.
Per below document, to clear the cache below are the options.
clear cache
To clear cached objects, use the clear cache EXEC command.
clear cache {cifs | dre}
clear cache http-metadatacache https {conditional-response | redirect-response | unauthorized-response}
clear cache http-metadatacache {all | conditional-response | redirect-response | unauthorized-response} [url]
Syntax Description
cifs |
Clears the CIFS cache. |
dre |
Expires the DRE cache. |
https |
Clears cache entries for HTTPS metadata cache response types. |
conditional-response |
Clears cache entries for conditional responses (304). |
redirect-response |
Clears cache entries for redirect responses (301). |
unauthorized-response |
Clears cache entries for authorization required responses (401). |
http-metadatacache |
Clears the HTTP accelerator metadata cache. |
all |
Clears cache entries for all HTTP metadata cache response types. |
url |
Clears cache entries matching only the specified URL. If the URL string contains a question mark (?), it must be escaped with a preceding backslash (for example, \?). |
Defaults
No default behavior or values.
Command Modes
EXEC
Device Modes
application-accelerator
Usage Guidelines
After you use the clear cache dre command, the first 1 MB of data is not optimized. The Cisco WAAS software does not optimize the first 1 MB of data after a restart of the tcpproxy service. The data that is transmitted after the first 1 MB of data will be optimized according to the configured policy.
The clear cache dre command may cause the system to reboot, but you are asked to confirm before the command continues and you are given a chance to save any configuration changes that have been made to the running configuration.
The clear cache dre command does not delete the DRE cache contents but expires it by removing markers in the content to prevent reuse. If you want to delete the cache contents, use the disk delete-data-partitions command.
Examples
The following example shows how to clear the CIFS cached objects on the WAAS device:
WAE# clear cache cifs
The following example shows how to clear the HTTP metadata cache for conditional responses:
WAE# clear cache http-metadatacache conditional-response
