SEP 12.1 RU5 for Linux client was installed on Linux servers.
Using TOP command, server administrators realized that rtvscand is taking significant percentage of total system memory. Percentage varies depending on physical RAM available on the system, but the amout of memory it represents is between 600 MB and 800 MB.
Rtvscand loads antivirus definitions in memory.
Without definition on the machine (e.g. before initial LiveUpdate), rtvscand would only use about 20 MB of memory.
This is working as designed. Rtvscand needs to load definitions in memory to protect the system.
