Fixed issues

Issue ID Description Fixed in
DEF93264 After an upgrade from Sophos Anti-Virus 7 to Sophos Anti-Virus 9 on HP-UX, the scanner reports an error.

After an upgrade from version 7 to version 9 on HP-UX, savscan returns an error message: "Error: Unable to locate SavForLinux installation directory." This happens if version 7 was installed with a directory that is not group 0. The upgrade to version 9 leaves this setting unchanged, but in this version savscan expects to find a directory that is group 0.

9.4.1, November 2013

Known issues

Issue ID Description
DEF95670 Enterprise Console displays the incorrect version number after an upgrade or downgrade between Recommended and Preview versions.

If you upgrade or downgrade between the Recommended and Preview versions of Sophos Anti-Virus, the product version number displayed in Enterprise Console is not updated. This is because these versions have the same threat detection engine and threat data (changes in the version number are reported only when the detection engine or data version changes). Enterprise Console will display the correct version number as soon as Sophos Anti-Virus receives an automatic update that includes new threat data.

- 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 www.sophos.com/en-us/support/knowledgebase/118805.aspx.

DEF74349 Enterprise Console does not show that a file has been quarantined.

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.

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 www.sophos.com/en-us/support/knowledgebase/58693.aspx.
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 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 www.sophos.com/en-us/support/knowledgebase/50230.aspx.
- 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.

PSALLOC=early

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.

Additional information
