The Symantec Endpoint Protection (SEP) client generates many folders in the C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\ErrMgmt\Queue\Incoming.
These files and folders consume a large amount of disk space.
The application or process crashes may not be related to SEP.
When SEP is installed, SymQual and Windows Error Reporting debug settings are added to the Windows registry. When an application or process crashes, files and folders are generated, and data is sent to Symantec. If the SEP client is unable to transmit this data to Symantec, these files and folders remain on disk and consume disk space.
Investigate other applications or processes that crash and implement a fix as necessary. This step stops any additional creation of files and folders.
To fully disable submissions and prevent data accumulation:
In the Symantec Endpoint Protection Manager, go to Admin > Servers > Local Site > Edit Site Properties > Data Collection.
Uncheck "Let clients send troubleshooting information to Symantec to resolve product issues faster."
Please note that even when "Let clients send troubleshooting information to Symantec to resolve product issues faster" is unchecked, logs for app crashes in the "Incoming" directory aforementioned may still continue consuming disk space. In such a case, please ensure to follow the other two resolution options mentioned in this article, including troubleshooting the root cause of application crashes and resolving those crashes, and lastly, if the root cause for application crashes cannot be resolved, disable SymQual (below).
Disable SymQual monitor
To disable SymQual's monitor for specific applications or processes:
