TMZ has obtained the 911 calls placed moments after Hollywood legend Ed Asner got seriously ill during a performance in Indiana Tuesday.
On one call ... the dispatcher says Asner was "sweating profusely" after getting sick during his one-man play "FDR."
Ed was taken to the hospital by ambulance.
The exact nature of the emergency is still unclear -- but as we reported, Ed's son says the actor has been feeling under the weather for a few weeks ... but is now doing fine.
Ed's publicist blamed "exhaustion."
