Question

a problem with and a matter of
I still think it's a problem with too much workload
I still think it's a matter of too much workload 
Are two sentences are same meaning? Both are correct?

Thanks a lot.

Answer

For me in the first sentence it's indicating that it is difficult to deal with or worrying about, while in the second sentence is being discussed with or dealt with about the topic.
