perl (assp) calls the executable of the products via a system call qx(). A thread is blocked (and out of control) while both are running. >On weekend I'm planning to migrate mail server, so I'll try to enable OCR plugin for a while and look whether is issue appears again... Only use the pdf-function, do not enable any OCR image processing! btw. to make tesseract usable, you have to learn tesseract how to do OCR (this has taken me 2 weeks)! OCR image processing is for those, who have much time, less emails and big systems. >appears again... Yes it will, if image processing is switched on !

Is tesseract and/or ImageMagic work within Perl process, or they start their own processes for image conwerting? Until I found a solve - plugin will remain disabled.

Read the documentation of both! I think you should not configure the usage of OCR (image processing) - extracting and analyzing the text from *.pdf files is OK. tesseract and imageMagic are running out of assp's control. If you have 4 CPU-cores 5 workers and 4 of them are processing images - the complete system will stuck!

Most of outbound mail get stuck in outbound exchange queue caused by strange behavior of ASSP. ASSP Worker/DB Status - not healthy convert and send data (stuck) - and loop age is grow up to 300 seconds and more... In this time ASSP (Perl.EXE) grows up in memory usage to 1.2-1.3 GB of RAM. Affected: 2.0.1_RC0.6.11 and 2.0.1_RC0.6.13 Have to fall back to 2.0.1_RC0.6.06 but the issue is appeared again. I haven't time yet to thoroughly look in to logs but the one line is pins my attention: Dec-11-09 11:13:42 18847-03932 [Worker_4] 192.168.10.210 <[email protected]> to: [email protected] ASSP_OCR: converted file image001.png is to large for OCR - skip I'm disable OCR plugin, restart ASSP and problems appears to be gone. 20 minutes later I upgraded ASSP to the latest version (2.0.1_RC0.6.13) and problem did not appear. What circumstances can provoke this behavior? Any ideas? The one and only thing I can accuse - is that I updated all Perl modules on this server two day before. But why ASSP takes full resource of one logical CPU and grows up in memory usage - is the goal question that I have to solve. PS. I can't reboot server right now... PPS. Server uptime - 40 days.
