OBN Issue

Hi guys,
I’m deploying an OBN server on GVP. After following each step by step I made it work one more step, however now I’m facing this problem:
OBN can receive requests and introduce them on to the DB, the process no longer crashes so frequently (due to a missconfiguration on SQL client) but still gives me this error:

[2009/05/11 18:54:58.406] 1D98 ORP.cpp:976 C=71:L=2:U=0 Exception in ORP::sendSuccessToQM() [2009/05/11 18:55:10.438] 1D98 ORP.cpp:160 C=71:L=2:U=0 Exception in ORP::startORP()

Have you seen such error? What could be ORP or QM?
Thanks
