Essence Drain started creating server lag and dc afterward (and map closure)

Hi,

Does anyone have problems on server site while using essence drain with contagious on good density map (or around unclaimed shrines I noticed)?

Sometimes when my DoT is spreading with contagious it creating spike lag, server tick every few seconds and then after ~20 sec there is DC or character is moving around with 5000% speed to catch up with actions during lag.

Worst part is that after DC map is closed, so if you had good map boosted with 3 tables and max exalted waystone it's still gone.
