Dear All:

I am using Gaussian 98 to do some optimization, but it stops 
after several optimization steps and give out the following error message:
 
   1 Symmetry operations used in ECPInt.
 ECPInt:  NShTT=   10585 NPrTT=   42446 LenC2=    7399 LenP2D=   18527.
 LDataN:  DoStor=F MaxTD1= 6 Len=  172
 LDataN:  DoStor=T MaxTD1= 6 Len=  172
 ECPSu allocation failure:  iend,mxcore=   1345271   1345270
 Error termination via Lnk1e ....

I am using pseudo-potentials for some elements. 
My question is: what's the error mean? why does the calculation seem
working  well in previous steps  but suddenly get crashed?

Thanks in Advance!

Zhenyu
