[syslog-ng] patterndb + format_json 100% CPU

Hi list, Running syslog-ng with self written patterndb and format_json output the process is hitting 100% of CPU looks like it's freezed (infinite loop ?) and nothing is written to the output. Follow the link to syslog-ng.conf, patterndb file and example logfile: syslog-ng.conf - http://pastebin.com/QD6huzA3 httpd.xml (patterndb) - http://pastebin.com/kF9zJHYH all.log - http://pastebin.com/syusGF2H Was possible to reproduce that with 3.4.4 and 3.5.0beta3.
