Are you running in 32-bit mode by chance? The memory levels make me wonder if you might be hitting the 32-bit limit on the system.
Could you try "encounter -64" to see if that resolves the problem? If so, you could set this UNIX environment variable in your .cshrc file to have the tool automatically start in 64-bit mode when running on a 64-bit machine:
setenv CDS_AUTO_64BIT ALL
In reply to Robert Dwyer:
Thank you very much Bob for the reply. I faced the same problem for many weeks and finally had solved it with your suggestion.
