Pending moderator requests page freezes with many emails

[SJ]

Mailman 2.1.9, Firefox 3 or Opera 9.64

Tend to Pending Moderator Requests page freezes when it has more than a few hundred emails.
First it will take about a minute to load the page incrementally. Then, once the page is finished loading, if I try to modify the radio buttons for any of the messages, after modifying 1-3 messages the browser will freeze. After another minute it will unfreeze.

If I try to scroll too far down the page, somehow it will freeze in the middle, and the browser will again become unresponsive... regularly not recovering at all, and requiring a browser restart.

I managed to moderate ~250 messages by loading only part of the page at a time, stopping it before it finished, and processing messages in batches. A list with more spam was unmoderatable, and I had to blindly discard all messages. This happens with both FF and Opera.

I think this must be an issue with either your web server, the network, your workstation or the browsers. I don't see how this is a Mailman bug.

The normal consequence of "too many requests" in the admindb interface is that the process times out before producing any output (it has to go through all the requests and sort them before it can build the page). Once the admindb CGI has built the page and produced its HTML output (which is done all at once with a single 'print' statement), it is done. If the output arrives at your browser in increments and the browser "freezes and thaws", this is between the web server, the network, the browser and the workstation on which the browser is running. It has nothing to do with Mailman until you ultimately click a 'submit' button.

My best guess is you should try a workstation with more RAM.

It seems that it's related to the server... I have a few hundred MB of
memory free when this happens.
