extraction phase-SUM is throwing error

Hi,

We are in the extraction phase of SUM and it has stopped in the same.

OS is AIX7.1/ORACLE11g/R3-4.7->ECC6

The error pointed in log is-

exec(): 0509-036 Cannot load program R3load because of the following errors:

rtld: 0712-001 Symbol guesses was referenced

      from module R3load(), but a runtime definition

      of the symbol was not found.

Any guesses to solve this?

Regards,

Gaurav
