What steps will reproduce the problem?
1. Install Gallery Menalto 3.0
2. Install modpagespeed
3.

What is the expected output? What do you see instead?

Memory consumption growing extremly fast, also there is a lot of connections 
with status CLOSE_WAIT. Yesterday I have installed this gallery and 
modpagespeed and today morning I found hang Apache server with 39G log. 
Houpfully it was only testing server. I suggest to not use this module in 
production - its dangerous. My friend also had the same problem on production 
server with Debian 5 x64. 

Output from error.log

Can you provide the X-Mod-Pagespeed version?  Please also describe the Apache 
MPM: are you using pre-fork?  Can you provide the URL of your web-site?  If you 
do, then we can test our changes against it.


This specific warning is likely a false warning -- in the SVN trunk this has 
been fixed and we plan to release a binary update today.

However we'd like to know more about your environment.  I did not know about 
"Gallery Menalto 3.0" but I presume you have an image rich web-site.

We are working on startup transient load problems with image-rich web sites -- 
it's our highest priority.  We have fixed several process/memory growth 
problems and we are continuing to work toward stability based on the data we 
are getting in bug reports such as this.  The more detail you can provide, the 
better.

Thanks!

Mod pagespeed version... 

I have downloaded my package from here: 
https://dl-ssl.google.com/dl/linux/direct/mod-pagespeed-beta_current_amd64.deb 


To test this mod You can use software which was installed on my server - 
Gallery Menalto. 
If mod_pagespeed_beta (and Gallery Menalto) is installed, Apache consuming a 
lot of memmory also I have found a lot of open connections with flag 
CLOSE_WAIT. 

Gallery Menalto: 
http://gallery.menalto.com/

Without mod_pagespeed_beta Apache consuming around 20mb during browsing gallery 
by one person.

We would like to confirm that we have fixed this problem with our latest 
release: version 0.9.8.1-215.  We have throttled the number of images that will 
be optimized at the same time.

If you still see this problem happening, please re-open and provide a URL.

Thanks, maybe in the future, when mod_pagespeed will be more stable. Right now 
I`m not planning to use this software on any of my machines. Good luck ! I will 
observe this nice software :)
