Yes I do use asynchronous submissions.  The submissions do come through after the server load is resolved, but I still get this major lock-up.  Very confused…

Hi Paul,

we switched to asynchronous submissions, when we experienced the problem. Since then, we never had any issues with this again.
Have you tried setting
in cdash/config.php?

I have an interesting thing happening on about a monthly basis.  A lot submissions to our cdash get stalled, mysql shows a load of 1, and response to web page requests gets very slow (on the order of 10 minutes or better.  I did a search and found a related topic (http://public.kitware.com/pipermail/cdash/2011-October/001046.html) but since I do not yet have automated removal running (I confirmed this in the logs as well) I am not sure what else might be doing this.  On 2 occasions, the problem resolved itself and on 2 others I was forced to restart the mysql and apache services.

I did find some issues with my xml submissions which created builds far in the future – I am fixing those, but I do not expect it to have created this type of behavior….

Any feedback anyone has would be very useful.
