SophosWebIntelligence assertion failed

What does it mean when the system.log files up with messages of the form:

  • Hey everyone,

    Ok, I managed to round up some details on this. 

    It's actually believed to be an artifact left over from one of the APIs we'll be replacing in a future version of SAV.

    The good news is that it shouldn't put your Mac at risk. If you experience a crash of the web service (as mentioned by Robr) there will be a very breif window during which content won't be scanned, but in most cases malware needs to be written to disk, so the on-access scanner will come into play and the crashed web daemon will automatically recover. 

     - That's not good. Do you find that your Mac is always slow now, or is it intermittantly? Have you noticed any correlation to other activities?

  • 4 months later, is a fix forthcoming? I still experience this, running the most recent version (9.2.7) on Yosemite 10.10.5. And yes, anything that does continuous syslogging is taking up valuable system resources (2 hours of CPU time shown here), and should be fixed!
