Status: RESOLVED EXPIRED

(Core Graveyard :: Plug-ins, defect)

Description

[Markus Berndt]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030630 WebWasher/4.4 fcs

After installing Adobe Acrobat Reader and copying the file nppdf.so into the
plugins directory, opening a pdf file with mozilla causes a very heavy load on
the X server. Here's some output from top to show this:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME CPU COMMAND
22531 root      17   0  304M  47M  4144 R    90.4  2.3   6:09   0 X

The plugin works, the pdf file is displayed correctly, however, the heavy load
reults in reduced responsiveness of the system.

This problem occurs with several versions of Acrobat Reader: 5.0.5, 5.0.7.


Reproducible: Always

Steps to Reproduce:
I use Redhat 9

1. Install the latest mozilla builds from rawhide (eg. 1.4-11)
2. Install Adobe Acrobat Reader 5.0.7
3. Copy nppdf.so from the acroread installation to /usr/lib/mozilla/plugins
4. open a pdf file, eg. http://cnls.lanl.gov/~shashkov/papers/burt.pdf

Actual Results:  
The X server is under heavy load.

Expected Results:  
After rendering the output there should be no significant load on the X server.

I have been having this problem with any GTK2 build of mozilla on RedHat, even
compiling from source.  The problem is also reported here:

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
