10gR2 RAC Database instance & CRS shutdown Hanging

Folks



Instance & CRS shutdown both seem to be Hanging for an internal Test
10gR2 RAC Setup.



What approach / action should be considered? Will O.S. RE-BOOT of Both
the Nodes in the Current State resolve the issues?



P.S.



Oracle version - 10.2.0.2

Solaris 10



On Node 1



Unable to shutdown the instance using srvctl & "shutdown immediate".
Both Hanging.



Following message is being repeatedly Written infinite Number of Times
to the "alert_PNBRAC1.log"
