We have a GWT 2.4 app that makes regular (every 5 seconds) async rpc calls 
to request data from an httpd/tomcat web server.  In Firefox and Chrome 
everything works as expected but in IE8 after a seemingly random amount of 
time the calls start to fail with one of two errors:

com.google.gwt.user.client.rpc.StatusCodeException: 12002
com.google.gwt.user.client.rpc.StatusCodeException: 12031

12002 is apparently an ERROR_INTERNET_TIMEOUT and 12031 is 
ERROR_INTERNET_CONNECTION_RESET

The app will work fine for only a few minutes, and sometimes it will work 
for up to a whole day..
When the calls start to fail, I see nothing on the web server side (in the 
httpd logs or using tcpdump I see nothing happening).

Has anyone run into anything like this before?  Any thoughts?

Thanks,
Ryan
