Different matrix mulP results on client vs server?

I am having a really odd problem with my code which I am having no luck figuring out. I have a piece of code where I multiple a vector and a matrix. I was getting some odd results sometimes so I started adding code to debug the problem. That's when I realized that a call to mulP on the server is returning a different resulting vector than on the client. I put together a simplified version which is below. This piece of code is being called from within Projectile.cc.

I won't waste space with all of the print output. Suffice it to say that the printouts for the server and client are the same except for the res vec

client resVec: 0.000932, 0.5000, 10927.51562
server resVec: 0.000932, -15154534289(really big number).0, 10927.51562

Any ideas on what could be going on?

MatrixF mat;
	Point3F vec1, resVec, row;

	row.set(0.98, 0, -0.19);
	mat.setRow(0,row);
	row.set(.1, 1, .1);
	mat.setRow(1,row);
	row.set(0.19, -0, 0.98);
	mat.setRow(2,row);
	
	vec1.set(0.0009, 0.001, 50.0);
	
	if(isClientObject()) {
		Con::printf("client mat:");
		#define idx(r,c) (r*4 + c)
		for (S32 r=0;r<3;r++) {
			Con::printf("    %f %f %f", mat[idx(r,0)], mat[idx(r,1)], mat[idx(r,2)]);
		}
		Con::printf("client vec1: %f, %f, %f",vec1.x, vec1.y, vec1.z);
		T_c_N.mulP(vec1, &resVec);
		Con::printf("client resVec: %f, %f, %f", resVec.x, resVec.y, resVec.z);
	}

	if(isServerObject()) {
		Con::printf("server mat:");
		#define idx(r,c) (r*4 + c)
		for (S32 r=0;r<3;r++) {
			Con::printf("    %g %g %g", mat[idx(r,0)], mat[idx(r,1)], mat[idx(r,2)]);
		}
		Con::printf("server vec1: %f, %f, %f",vec1.x, vec1.y, vec1.z);
		T_c_N.mulP(vec1, &resVec);
		Con::printf("server resVec: %f, %f, %f", resVec.x, resVec.y, resVec.z);
