After adding the Announcements and the Events modules onto the same page with one Text/Html module, the server could no longer access the website which is a child portal.  It would try to load the page for several minutes before giving an out of memory error.  I uninstalled the Announcements module from the module definitions including file deletion, and that solved the problem, we are able to access the child portal again.  But, the odd thing is that in the Event Log there are no errors relating to the Announcements module.  The exceptions are reported on the Events Module.  Not sure if it's all related or if we had several different problems going on at the same time that culminated in the out of memory errors or just what is going on.  We are using DNN 4.09.00.  The announcemts module was 4.00.01 and the events module is 4.00.02.  Neither of those modules had any data entered yet.  Access to the website was lost before any announcements or events could be entered.  The Text/Html module had some basic text entered.  Nothing fancy on the page, just those three modules in standard installation sql 2000 server.   Something else to note, we have the same setup on another website which is a separate install of DNN on a different server that has only one portal, that being the main one, and the events and announcements modules behave fine on the same page.  It's just in this website where the modules are installed together on the same page in a child portal.  There are only 4 portals, three being child portals and they all have very little data if any in them right now.  Below are two of the exceptions as they were logged:

Actually, after deleting the Announcements module everything was working, so I tested again with the Announcements module v4.00.00 and tried installing the announcements and events modules on separate pages.  It was working until I placed the announcements on the home page again.  If there is an error in the code on the page, it would have to be something with the core code for  the modules as nothing is customized on the page.  The modules are placed but no content has been added.  At first, the pages load fine, but after clicking back and forth a few times between the page with the announcements module and any other page, the timeouts and memory problem starts in again. 

If there is a bad date in a cookie, how would that effect the page functioning for another user on a different computer?  Or is the announcements or events modules placing bad cookies on every visitor's computer?

It seems like it is the announcements module causing the conflict, so maybe this should be moved to the announcements module forum...

Hi Rick,

If you can package up your site, so we can install at this end and debug against it, we can try to fix. But other than that I have been unable to replicate the issue. One other thought, have you tried testing a standard skin on that page, to see if that is causing the problem. If it is, you may be able to just send the skin, and see if I can debug what is causing the problem.

Cheers
Roger
