Rovo "Input Too Large"

Am I trying to overwork Rovo?!? :) 

I have an agent I created to help with root cause analysis over a time period (i.e. prior month or quarter). I'm still in the process of testing and refining my prompt and output, and I'm more often than not getting "input too large". Weird thing is, I can set it aside and come back in a few hours and then it works just fine. Any thoughts here? Am I correct in thinking that my agent instructions might just be too large and Rovo is timing out?
