symcscan.exe is consuming high memory even when Symantec Protection Engine (SPE) is not running any scan
SPE 8.2.x
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 8.1.10.121 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.
