Issue ID Description
- Per-process memory limits on UNIX systems can restrict Sophos Anti-Virus from functioning correctly

On IBM AIX systems, Sophos Anti-Virus requires more memory than the default "Maximum Data Segment" size limit. For information on how to increase this limit, see

DEF82357 If you run savscan on the current directory by typing:
savscan . 

and the directory contains a threat, and the threat file is not readable by any of the current user's groups or the sophosav user or group, savscan detects the threat but fails to determine the path of the file and displays the following error message:

Failed to canonify path: <filename> as no cwd available.

If the command-line option -remove is used with savscan, removal of the threat does work. You can workaround this issue by specifying the full path of the current directory instead, when you run savscan.

DEF74324 On HP-UX, if you try to get help on the uninstall command, for example by typing: --help

Sophos Anti-Virus is partially uninstalled. To workaround this issue and uninstall Sophos Anti-Virus:

  1. Re-install Sophos Anti-Virus with the command-line option --ignore-existing-installation.

    Sophos Anti-Virus is now fully installed again.

  2. Run without the option --help.
DEF74339 If you install Sophos Anti-Virus on a virtual machine for the first time, and you use Sophos Enterprise Console to schedule a scan on that machine, the scan runs twice. Subsequent scans run only once as normal.
DEF74349 On a Sophos Anti-Virus installation that is managed by Sophos Enterprise Console, if an on-demand scan quarantines a file, savlog shows that the file has been quarantined, but in Enterprise Console, "action taken" is blank.
DEF52913 On AIX, the output from savscan is in English, regardless of the system language.
WKI42035 If you install a managed installation of Sophos Anti-Virus on an AIX or HP-UX workstation, and in Sophos Enterprise Console you move the workstation from the "Unassigned" group to another group, the "Anti-virus and HIPS policy" column in the computer list might display "Differs from policy". To work around this, in Enterprise Console, right-click the workstation, point to "Comply with", and then click "Group anti-virus and HIPS Policy".
DEF38027 During installation or upgrade, if you make typographical errors when prompted for information, and correct these, control characters might be stored as part of your input. This could cause a problem, especially with updating. For more information, go to
DEF29605 On a computer running Solaris version 10 with a Japanese locale, if you try to install Sophos Anti-Virus from a central installation directory and you enter an installation location using Japanese text, the installation fails with the message "svccfg: Syntax error".
DEF23317 If you install Sophos Anti-Virus on a computer that has Sophos Anti-Virus version 4 and a third-party product that uses SAV Interface installed, you might have to configure Sophos Anti-Virus to use the correct location for the Sophos Anti-Virus libraries and threat data. For information, go to
DEF20663 If a workstation is shut down uncleanly, and Sophos Enterprise Console has issued policy changes, the changes are not applied to the workstation when it restarts.
- Sophos Anti-Virus on AIX and SAV Interface on AIX.

On AIX, it is possible for the memory allocation functions to return memory addresses that don't exist, usually when the computer is running low on memory. If these memory addresses are subsequently accessed, the computer may terminate the application.

Sophos recommends setting the PSALLOC environment variable to the value "early", before running Sophos Anti-Virus on AIX or SAV Interface applications on AIX, i.e.


Setting PSALLOC to "early" causes the memory allocation functions to only allocate memory that exists. This may cause your computer to run slower, because further checks are carried out on memory as it is allocated.
