Insufficient Memory

I posted the question in a web site:
http://salvo61.wmg.warwick.ac.uk/public_html/flextool/math/link.html
The commands of Mathematica is straight forward,
[1]<<Input1  {load file Input1, which can be found in the web site}
[2]<<try     {polynomial files with long parameters and one variable t1}

[3]NSolve[%,t1] {Solve <<try with solutions in t1}

The problem posted in the web site:
Mathematica commands (Input1 & try are text files),
<<Input1 - (This file contains the values for all the parameters in try,

e.g. {mx1=225.71948780422000, and so on}
<<try  (This file has around 7 M, it accepts all the values from Input1
and forms a polynomial equation with one t1 variable.
In short form, try is an equation in n1*t1+n2*t1^2........n16*t1^16==0)
<<NSolve[%,t1] (will suppose to solve the equation with 16 solutions.)

1) Can anyone help me to check the solutions of NSolve and send me the
MemoryInUse[] and MaxMemoryUsed[], and also
the results of t1. Thanks.
2) Can anyone get one value of t1 = 1.076668643315930.
3) I suspect my server doesn't have enough memory to run the program, is

there any method to validate my assumption?

Best Regards,
Chai
