Clamd stops working

Symptoms :

  • Certain mail are rejected.
  • /var/log/maillog contains following lines for those mail :
clamdscan: corrupt or unknown clamd scanner error or memory/resource/perms problem - exit status 512/2
  • /var/log/clamav/clamd.log contains following lines :
Not supported data format ERROR

Cause :

  • Clamav cannot recogize and scan one of the attachments contained in the mail. Typically this will be a zip file of old format such as some old pkzip version.

Solution :

  • Apply the patch mithi-patch-clamav_unsupported_zip_file-p1- which patches the qmail scanner to ignore the 'Not supported data format ERROR' received from clamav.
