Intermittent error when previewing reports

This is a problem that started a few days ago, but I have no idea why. On occassion, in the report preview window, an error message is shown in the preview window.

Looking at the tomcat logs, I saw the following stacktrace:

java.lang.IllegalStateException: Report could not be loaded. It might be that ReportServer cannot access its temporary files (specified in rs.tempdir). If this error occurs repeatedly, please contact an administrator.

this comes with a corresponding entry in our access logs:

"GET /reportserver/reportserver/reportexport?nonce=0.5806268271986663&tid=15-12-1392793701350-32892745&isJsViewer=true HTTP/1.1" 500 4930 "http://xxx.xxxx.xxx/reportserver/resources/pdf.js/pdf.js" "Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko"

So I looked at the tempdir setting in the reportserver filesystem at /etc/main.cf and changed it from "tempdir" to "/tmp" and did a config reload.
I checked the /tmp directory and can see temp files now being created in /tmp.

But I am still getting a similar error:

The temp file reportserver is looking for doesn't exist in /tmp and I have no idea why/where it is getting it from. Is this an old preview that is being cached somewhere? Is there a way to clear it? I have tried re-starting tomcat, but that didn't help at all.

The random error messages look bad from an end-user point of view and the multiple error 500 messages are triggering our intrusion detection system.
Any thoughts on how to diagnose/fix this problem?
