Admin->Content->Pages throws server error 500 on large site

[tmk]

I have a site with about 1800 pages (based upon count of the contents table records)

If I'm in the admin panel and click on the Pages link to view/edit pages, I get a server error 500. It does not appear to be a timeout since it returns the error quickly.

The site otherwise works fine. The public can view all the pages, I can do all other admin duties, but can get the Pages link to work without the server error. This hapened after I added a whole bunch of pages.

I was spelunking in the listcontent.php file trying to find something that I could fix. I see that it uses xajax (mabe the problem is there?)

I do have other CMSMS sites on the same server with far fewer pages that are fine. So I'm thinking I'm exceeding a limit somewhere, whether it's memory, a parser, or something else.

Any insight would be helpful.

BTW, Memory limit in phpinfo is 40M

double your memory limit or more and see if that fixes it.
