SQL: -208: Memory allocation failed during query processing

Environment:
Perl v5.8.4 built for sun4-solaris-64int [SunOS 5.10]

Perl DBI uses Informix DBD, DBI connect and prepare statement are successful, execute routine returns error: SQL: -208: Memory allocation failed during query processing

The same SQL query works fine and returns results in other environment. Can you please suggest if the issue is with DB engine or Informix driver in Perl?

Thanks,
Ram
