Hello All!
So, thanks to the help of the community  I solved my last problem which was due to disposing of a handle which led to the gc() not being comprehensive.
All sorted!
Now I went to fix another issue (just one me picking up the wrong field as I record my results), and I ran into a very very strange one. Strange enough I think it might be a bug  but if not (or so) any workarounds anyone can offer me are muchly appreciated.
For more comprehensive code of mine you can see the last thread I wrote, but I don't think that's relevant. Here is a single difference which causes me to either run out of memory (leak), or otherwise complete successfully.
The code with the memory leak is 
DynamicVector testvar5 = rEngine.GetSymbol("mNames").AsVector();
NumericMatrix testvar14t = rEngine.GetSymbol("mCoef").AsNumericMatrix();
for (int i = 0; i < testvar14t.RowCount; i++)
{
__ //got to 5th x on the below
//string tempIvN = "(Intercept)";
//just up to 1st on this sucker
string tempIvN = testvar14t.RowNames[i];__
Single coeff = (Single)testvar14t[i, 0];
Single pvalue = (Single)testvar14t[i, 3];
if (Single.IsInfinity(coeff)) coeff = 0;
if (Single.IsNaN(coeff)) coeff = 0;
if (Math.Abs(coeff) < 1.0E30) coeff = 0;
if (Math.Abs(coeff) > 1.0E30) coeff = 0;
if (Single.IsInfinity(pvalue)) pvalue = 1;
if (Single.IsNaN(pvalue)) pvalue = 1;
if (Math.Abs(pvalue) < 1.0E30) pvalue = 0;
DataRow oprNewRow = regnTable.NewRow();
oprNewRow["SEC_ID"] = sid;
oprNewRow["DAT_ID"] = c;
oprNewRow["LINDEX_ID"] = x;
oprNewRow["IVR_INDEX_ID"] = indVarCodes[tempIvN];
oprNewRow["IVR_INDEX_COEFF"] = coeff;
oprNewRow["IVR_INDEX_PVALUE"] = pvalue;
regnTable.Rows.Add(oprNewRow);
}
testvar5.Dispose();
testvar5 = null;
testvar14t.Dispose();
testvar14t = null;
Switching around the comments, where the code works :
NumericMatrix testvar14t = rEngine.GetSymbol("mCoef").AsNumericMatrix();
for (int i = 0; i < testvar14t.RowCount; i++)
{
__ //got to 5th x on the below
string tempIvN = "(Intercept)";
//just up to 1st on this sucker
//string tempIvN = testvar14t.RowNames[i].ToString();__
Single coeff = (Single)testvar14t[i, 0];
Single pvalue = (Single)testvar14t[i, 3];
if (Single.IsInfinity(coeff)) coeff = 0;
if (Single.IsNaN(coeff)) coeff = 0;
if (Math.Abs(coeff) < 1.0E30) coeff = 0;
if (Math.Abs(coeff) > 1.0E30) coeff = 0;
if (Single.IsInfinity(pvalue)) pvalue = 1;
if (Single.IsNaN(pvalue)) pvalue = 1;
if (Math.Abs(pvalue) < 1.0E30) pvalue = 0;
DataRow oprNewRow = regnTable.NewRow();
oprNewRow["SEC_ID"] = sid;
oprNewRow["DAT_ID"] = c;
oprNewRow["LINDEX_ID"] = x;
oprNewRow["IVR_INDEX_ID"] = indVarCodes[tempIvN];
oprNewRow["IVR_INDEX_COEFF"] = coeff;
oprNewRow["IVR_INDEX_PVALUE"] = pvalue;
regnTable.Rows.Add(oprNewRow);
}
testvar5.Dispose();
testvar5 = null;
testvar14t.Dispose();
testvar14t = null;
It's as if looking at " string tempIvN = testvar14t.RowNames[i].ToString(); " is killing me.
Why could this be, and how can I work around it ?
THANKS
