Hello Everyone,

Hello Everyone,

I was wondering if any body has come across the following issue or if
one of you can throw some light on it.

We provide files to view/download on our website. Some time when the
users try to view (by clicking on the link of the document, which will
open the file in a new browser window) they get an error message (it is
custom error message we are showing whenever there is an error) and the
log files show the following stack trace. 

This is not consistent all the time, we randomly come across this
issue. If we restart the server, the issue disappears and will probably
happen after a couple of days (once in a while). After the restart users
are able to view/download these files. These files are mostly PDFs and
some MSWord Docs.
