I have not been seeing any serialization errors, but perhaps my code is eating them somehow.
The pages where my app uses Ajax are fairly complicated, but it does exhibit the problem on all of them. I will try to add the debug info flag from below and make sure I am not eating any exceptions. As Chuck suggested, I looked in ERXAjaxSession, but it does not seem to have any serialization related code or transient variables that should make any difference. Hopefully, I am just eating a serialization exception. I will report back after I do some more investigation.
