Appliance does not allow to run PDF reports

Summary

When tried to generate report and sent it out via email, there's an error message: file/temp/exreport_(devicename and date&time).pdf does not exist or is not a regular file ...

Overview

When you try to email the report, the following message appears.
Error: File /tmp/pdfreport.pdf does not exist or is not a regular file

The report that is sent out has nothing in it (0 kb) and damaged. Adobe is unable to open it.

Cause

When generating report, the process nodepdf in the appliance is listening on port 1337 and the following lines are expecting:
-info: HTTP server listening on port 1337 at localhost.
tcp 0 0 0.0.0.0:1337 0.0.0.0:* LISTEN 2296/node

Workaround

1. Are there any notifications regarding /var partition utilization is high?
2. If no, please login Web GUI by a local admin account and try to generate PDF report again.
3. If it is still not working, go to check the log and find some lines like these:
