On Windchill 13.0.2.4. I have seen this many months ago so not a huge issue. It might be related to a customization we added to process representations from WTDocuments but here goes. User got an error message "No Space Left on This Device". Sure enough /tmp was at 100% of 1GB. Looking in folders, the Windchill temp folder was filled with 500+ font files with the pattern jr-font<some number>.ttf. These are about 0.5 MB each so eventually it filled up. I cleared out these files but I am sure to see this again. Any idea as to what its doing and why they are not being cleaned up. I suspect its related to something we added but just a quick guess.

I will have to see which jasper reports are generating these but I think you have nailed the cause. Surprised I did not see this before. Strange that it only looks for them to clean up on startup/shutdown events. This means that if you run for a long time, it could fill up. I suspect a cron job to clean these is needed.
