[AMaViS-user] SAVI glibc 2.2 version

I use Courier MTA, SAVI as the virus scanner and a Debian system with glibc
2.3.2 (heavily patched as all distros' libcs are).
In testing amavisd-new 2.3.2-pre1, I discovered that all messages were being
passed as clean by amavisd-new, including those containing EICAR-AV-TEST,
and in the log there was:
ask_av (Sophos SAVI) result: CLEAN p001: error scann
ing file /var/amavis/amavis-20050601T210341-20139/parts/p001, Sweep could
not proceed, the file was corrupted (538) No such file or directory

In fact this occurred with amavisd-new 2.3.1 as well so I am fairly sure
that it is not amavisd-new's fault. Initially it occurred with SAVI 3.93; I
then upgraded to SAVI 3.98 and the problem persists. All the above is with
the glibc 2.2 version of SAVI. However I tried the non-glibc 2.2 version of
SAVI and it works correctly.

Scanning the file manually with sweep, with a simple perl -e script to call
SAVI, and even by copying Amavis::AV into a script and calling
sophos_savi_init, sophos_savi_internal directly all find the virus with both
SAVI variants, so it could be related to threading.

This looks as though it could be connected to

http://www.vanja.com/listarc/vtools/...ay/001750.html
although there should not be a problem with user permissions, as even the
very first amavisd-new process is started as the daemon user and amavisd-new
never drops privileges.

Has anyone else had trouble with the glibc 2.2 version of SAVI?
