Error in Clustering procedure

["Joao Baptista de O. e Souza Filho" <nash@lps.ufrj.br>]

Hello,

I'm working with SPLUS 6 in Windows 2000 SP4 (512MB RAM).

My data set is a matrix with 7000 events of 8 variables. I have
to do an aglomerative clustering. I select appropriate option though 
menu and the program starts calculating it.  At the end, I receive 
the following error message:   

========================================================================
Error in disv == -1: Unable to obtain requested dynamic memory (this 
request is
for 200194252 bytes, 0 bytes already in use
========================================================================

How can I solve it?

Thanks
