symcscan.exe is consuming high memory even when Symantec Protection Engine (SPE) is not running any scan
This high memory usages is because "buff.current" file loaded in memory for URL filtering/reputation.
If symcscan.exe is experiencing high memory usage, please check below conditions:
1. URL filtering feature is disabled
2. C:\Program Files\Symantec\Scan Engine\Definitions\Stargate\data\sef\webpulse_cache\buff.current file present.
If above conditions are met, then perform below steps to fix High Memory usages in Symcscan.exe service:
1. Stop Symantec protection engine service from service controller
2. Delete <stargate_home>\data\sef
3. Start SPE service.
Note: stargate_home=C:\Program Files\Symantec\Scan Engine\Definitions\Stargate
This workaround will work only if the Stargate engine is at 184.108.40.206 version and above.
If URL filtering/reputation is enabled then High memory usage is expected in SPE service even if SPE is idle. And this is normal.
Note: It is advised to add approximately 4 GB of additional physical memory if URL Reputation/URL Filtering feature is enabled.
