OutOfMemoryException

[viveknuna]

I am using this library 1.2.2 version in my windows service app, sometimes It's giving the below error and my application crashes.

Am I doing something wrong here? Can I fix this in my code? I want to keep updating the library to the latest version as the last option as it's a stable service and running for years.

this is the place where it gives the exception.

var context = new ExpressionContext();

context.Variables["Prop1"] = _rateExpression.Prop1;
context.Variables["Prop2"] = _rateExpression.Prop2;
context.Variables["Prop3"] = _rateExpression.Prop3;
context.Variables["Prop4"] = _rateExpression.Prop4;
context.Variables["Prop5"] = _rateExpression.Prop5;
context.Variables["Prop6"] = _rateExpression.Prop6;
context.Variables["Prop7"] = _rateExpression.Prop7;
context.Variables["Prop8"] = _rateExpression.Prop8;

try
{
    return (decimal)context.CompileDynamic(_rateExpression.Formula).Evaluate();
}
catch (Exception ex)
{
}
