Actually... I planned for magic overloads / outburns to happen some times to her. You can say that her body IS resistant to magic, but the magnitude of the magic she uses is also higher than usual, so she is prone to magic outburns if she doesnt mind her own magic usage.

As for the mana thing, she doesnt have any control about it. She doesnt "control" an arcane node, she simply IS a node. Limiting the magic is a conscious action, of course. As for her, limiting other witches' magic is indeed very tiring for her. Shai is currently breathing heavily, knelt down on the forest floor. For the time being, she is too tired to get up (Running, casting a powerful time shift and a ward to limit its effective range, placing a limiter on the magic flow around the area... Although it would still take, at least 2 big scale magics to an Arcane Outburn to happen, her body IS physically tired due to everything that happened.)
