Powerware LanSafe Memory Leak
Powerware LanSafe leaks memory, eventually consuming all of the available RAM and paging file, and rendering a system inoperable.
The module in question is C:\Program Files\Powerware\LanSafe\Bin\LSTrayAgent.exe which leaks 4Kb memory approximately every 10-11 seconds (roughly 1Mb every 45 minutes). This has been observed for the 5.x series and 18.104.22.168. LSTrayAgent.exe is present in versions from 22.214.171.124, but not included in earlier 5.x versions such as 126.96.36.199 and 188.8.131.52.
To resolve, use one of the following methods:
- Upgrade LanSafe to 184.108.40.206 or better. (NB. LanSafe 220.127.116.11 also resolves a problem detecting USB devices under 64-bit Windows Vista/2008.)
- Use Sysinternals' Autoruns to disable (or remove entirely) the automatic execution of LSTrayAgent, which launches from HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run (under the Logon tab). Then reboot.
- Delete C:\Program Files\Powerware\LanSafe\Bin\LSTrayAgent.exe.
