I noticed that it generates the following error in alert log:
Errors in file
/phx11dbt1/u01/app/oracle/admin/vtwdmas/udump/vtwdmas_ora_6462.trc:
ORA-07445: exception encountered: core dump [VxBSAGetData()+716] [SIGSEGV]
[Address not mapped to object] [0x000000DF8] [] []
The tracefile has the following message but the sbtio.log doesn't have any
information as the size of sbtio.log is 0.
SKGFQ OSD: Error in function sbtread2 on line 1156
SKGFQ OSD: Look for SBT Trace messages in file
/phx11dbt1/u01/app/oracle/admin/vtwdmas/udump/sbtio.log
Exception signal: 11 (SIGSEGV), code: 1 (Address not mapped to object), addr:
0xdf8, PC: [0xffffffff7d736d94, VxBSAGetData()+716]
Couldn't locate any note in Metalink related to this error. Any suggestions
will be appreciated.
Thanks,
Ashoke

Have you checked the alert log for the database you are trying to duplicate to?
Oracle has a couple of bug reports for unexpected channel terminations but
you'll need the error from the alert log file to narrow it down.

Subject: RMAN duplicate is failing : database session for channel
<channel_name> terminated unexpectedly
Hello all,
I am trying to duplicate a 3TB database, which has 927 datafiles. It is failing
with the following error. Some of the google notes refers me to work with the
backup media vendor. I have contacted Netbackup vendor Symantec but has not got
a solution yet and wondering if anyone from this list experienced similar
problem and have some recommendations.
Database version: 10.2.0.4
Netbackup client for Oracle: NetBackup-Solaris10 6.5.5
OS: Sun Solaris 10.
Channel aux4: reading from backup piece /incr0_TWDMAS_365890_776372926_a2n4d0lu
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 03/19/2012 09:50:58
RMAN-03015: error occurred in stored script Memory Script
RMAN-10038: database session for channel aux1 terminated unexpectedly
BTW: I am able to duplicate many other databases (all smaller than this
problematic one) to the same UNIX server without any problem. Not sure if the
size or the high number datafiles in backup is causing any issue or not.
Thanks,
Ashoke Mandal
