Dear Molpro users,
                           I am trying to run CCSD(T)/cc-pvtz for a large
system which contain 24 atoms with open shell . The problem is when I try
to run, it ends with memory issue. Kindly help to solve this problem by
giving your suggestions. I have pasted the input below.

*** Title
memory,5500,m
gthresh,orbital=1.d-5
gprint,basis
gprint,orbital
geomtyp=xyz        ! use cartesian coordinates xmol style
geometry={
24              ! Number of atoms

geometry specifications

BASIS=cc-pvTz
 rhf

 UCCSD(t)
---

I have pasted the error below


Eigenvalues of metric

         1 0.698E-06 0.165E-05 0.476E-05 0.511E-05 0.910E-05 0.118E-04
0.273E-04 0.314E-04


 Contracted 2-electron integrals neglected if value below      1.0D-13

I have increased the memory from 1000-5500, but still the job comes out
with error.
