Update. I have reverted to build ASSP_OCR,v 1.25 2010/10/15 15:00:00 and that is working fine without any worker hangs.....plugin set to block.
It is scanning incoming & outgoing images & pdf's OK.

If the version is less than 2.01 -> upgrade. Even with the new plugin, in most cases the current OCR implementation of assp is useless. The reason is simple. Spammers who uses images to deliver spam, never uses machine (OCR) parseable images. It is also very easy to compromize a system with an very high compressed image (1MB -> 30MB) - doing OCR on a 30MB image take simply tooooo long and uses 100%cpu for a tooo long time. There are other, much better technologies available to detect a 'spam-image'. I'm still analyzing, how this could be implemented in assp. These technologies are analyzing several different attributes of the image (size, color deep, is photo, is icon, is captcha, is screenshot ....?). I also think that spammers will not generate a large amount of different images (except captchas). So a centralzed database (like GRIPLIST) of image checksums would help to detect those images very fast. I'll start a new thread 'assp image processing' - I'm highly interested in ideas, hints, code or codefragments related to this problem.

I've disabled the ASSP_OCR Plugin and it's no longer hanging the worker. It scans pdf's OK, issue is with images, .png & jpeg. ASSP version 2.1.2(12002), activperl 5.014002. 5.10 was completely uninstalled and the old Perl dir removed. W2K8R2SP1 Imagemagik 6.7.3-4 Q16 Nothing in the log after it says scanning the file...that's when it hangs. All perl modules are up to date, apart from snmp agent, which I still cant get to install...:( can't find snmp.lib Any help would be appreciated.
