Kevin, Arjen, all:

If you're interested, we found the cause of the freshclam SysLog issue. The source ended up being an issue with our autotools build system and how we link freshclam.
If any of you are willing to try this patch, it'd be nice to hear how it goes. In our testing the patch solves the issue.

IMPORTANT: Because this is a change to autotools, you'll have to test this on a machine with autoconf, automake, m4, libtool, and pkg-config installed and you'll have to run autogen.sh to regenerate the autotools stuff before running the build.

Patch follows:

Interesting find! Yikes! Ok we'll take a look at it.

Please keep the feedback coming!

Correction: *almost* all is well again. Freshclam doesn't log anything to syslog after startup anymore (updates for instance). So unless I missed updating a setting, this is broken.

LogSyslog yes
LogFacility LOG_MAIL

This setting used to work as expected up to and including 0.102.4

Patch applies cleanly, running ./autogen.sh is successful and logging
of freshclam is back to what it used to be. Thanks!

DefaultMemoryAccounting is enabled in openSUSE Tumbleweed. One
observation I still have, is that the memory usage of
freshclam.service seems to steadily increase after each update. Since
this morning, it has increased from 1.5 MB immediately after startup
to 6.0 MB about 4 checks later. I'll keep monitoring this to see if it
levels off or keeps increasing.

After downloading daily.cld, memory usage went up to 340.1 MB. It
seems either systemd incorrectly reports the memory used, or memory is
not free'd after use somewhere.
