The SAV For Linux client fails to update its definition through Java LiveUpdate (JLU).
This is typically caused by corrupted virus definitions from a previous LiveUpdate session. These files can be found in /tmp/, under the path listed in the log, such as: /tmp/1238752304915/1237326853jtun_sav10ennful25.lin.
Delete the files shown in the log with <ldsFileAlreadyPresent>
The Connect article SAV for Linux: A (Somewhat) Illustrated Guide Part 3 focuses on how to keep SAV for Linux up-to-date. This article may be of interest to Linux admins encountering difficulty with LiveUpdate.
