As per wrobbins suggested, splitting the volumes up could be the best option.
If not, you might want to try this setting:

I had seen it working for both Netapp or EMC filer, not entirely removing the symptom, but some streams that used to error out with status 42/41 tend to complete.

can you split backup into multiple streams, i.e. /SSGROUP/somedir and /SSGROUP/otherdir

As watsons & wrobbins suggested,
I found in /SSGROUP there are total 33 dir hence i modified backup selection by each dir
but still one stream taking 2 attampts to finish with same error as mentioned below & other 32 stream finished in 1st attampt without any errors
/SSGROUP/Accounts & Finance
4/6/2011 6:24:20 PM - positioned 0385L4; position time: 00:00:04
4/6/2011 6:24:20 PM - begin writing
4/6/2011 7:36:14 PM - Error bpbrm(pid=8256) db_FLISTsend failed: file read failed (13)
4/6/2011 7:36:15 PM - Error ndmpagent(pid=8564) terminated by parent process
4/6/2011 7:36:15 PM - Error ndmpagent(pid=8564) NDMP backup failed, path = /SSGROUP/SSGROUP/Accounts & Finance
4/6/2011 7:36:16 PM - Error ndmpagent(pid=8564) NDMP_LOG_ERROR 0 Backup is aborted.
4/6/2011 7:37:37 PM - end writing; write time: 01:13:17
After that
I also worked as per TN and created NDMP_PROGRESS_TIMEOUT & restarted job.
Thankx to all for your help & will keep posting with updated status .
