[Kolab-devel] ClamAV signature update caused clamd crash

The ClamAV signature update daily.cvd 10938 causes a segmentation
fault in all ClamAV versions older than 0.96 (as used in Kolab
Server) on 32 bit systems.

A new signature update was issued shortly afterwards, but since
Kolab Server is configured to update the signatures every full hour
by default, it is very likely that your clamd crashed, too.

Delivery of mails with attachments (HTML mails fall into this
category) was not possible until the second signature update,
because the fallback mechanism (using "clamscan" instead of the
daemon) was affected, too.

Please verify if clamd is no longer running, e.g. with
"ps ax|grep clamd" and start it again as user kolab or user root:

  /kolab/bin/openpkg rc clamav start

Otherwise the much slower fallback mechanism will still be used.
