We focus on the behavior of conserved charge fluctuations. We show that in non-equilibrium the specific heat and charge susceptibilities diverge as the system crosses the isothermal spinodal lines.4 pages, 1 figure, to appear in the proceedings of Chiral07, November 13-16 2007, Osaka, JapanHigh Energy Physics - PhenomenologyNuclear Theorytext
