Linux may stop responding or perform extremely slowly after upgrading SEP Linux Agent.
Repeated entries appear in /var/log/sdcsslog/amdlog/sisamd_0.log:
<error> [AMDSefScanner::ScanFile]:235 SEF::CmdScan failed. error: 0x80020001
The upgrade process is not properly removing old files and causing a conflict.
SEP Linux Agent
Supported Linux operating systems
This has been resolved in SEP 14.3 RU2 and later. That is, if the installed version of SEP Linux Agent is RU2 or later it may be upgraded without issue. If the installed version is older, uninstall completely before replacing it with newer version.
