My Splunk-Light instance (free license) cannot generate PDF reports. It can still export reports to CSV and my license usage is around 150MB/day.
Splunk-light version is 6.6.1
I found the following entries in the pdfgen.log

Still have not resolved this issue - I have tried updating the splunk-light to latest version but still the same results. I am also having license warnings:
This pool has exceeded its configured poolsize=0 bytes. A warning has been recorded for all members
This pool has exceeded its configured poolsize=524288000 bytes. A warning has been recorded for all members
I think the probable solution now is to reinstall splunk-light.
