How to resolve agent iteration and time limit error

Hello,
My input is a CSV file which stored in a dataframe and I am trying to get responses from it using Langchain.
I am using the pandas_dataframe_agent . After first time execution of agent, I do get a correct response, but multiple executions is returning the error “Agent stopped due to iteration limit or time limit.”
Seeking some advice/suggestions from the community to resolve the error.
