Hello! I am really hoping someone can help me figure this out. I am  
hitting this intermittent error. It doesn’t always happen when I am  
doing a delivery action, but it happens sometimes. Its not always  
against the same action (contactEmail) below, but I’ve seen it  
sporadically across 3 other mailing actions. It’s tough to reproduce,  
but is definitely causing me some big problems!

Because the stack level is too deep, I feel like I’m not able to see  
the entire error. If you can offer any ideas or insight, I would  
greatly appreciate it!!

Rails 2.1.0  
ar\_mailer 1.3.1
