Please always mention NBU version and OS on NBU master and media server.
This is extremely relevant as various improvements have been introduced across different NBU versions.
Is PureDisk used here as NBU MSDP or separate Puredisk server?
Are you using Media server dedupe or client-side dedupe?
What is Client Read Timeout on media server?
Do you have bptm, bpdm and bpbrm log folders on the media server?
And logging level set to 3 (minimum)?
Are you only experiencing problems with long-running backups and smaller backups going through successful?
Have you checked KeepAlive settings on master, media and Oracle client?

Master Server : NetBackup-RedHat 2.6.18 7.6.0.3
Netbackup Appliance 5220 (Media Server) : NetBackup-SuSE2.6.16 7.6.0.3
Appliance Version is 2.6.0.3.
We are using Media Server Dedup Pool.
Client connect timeout settings is 9000 seconds
Client read time out settings is 7200 seconds
Logging level is set to minimum
This is mostly seen while taking full backups which is taken during weekends.
Where and how can I check the Keepalive settings.
Also in these cases how can I validate the data which is backed up.Because what I can see is oracle jobs runs in batches triggered via the RMAN script. The subsequent jobs runs successfully. I wonder how is it running in batches , is this defined at netbackup end or in the RMAN?
I have taken the logs only for 19, attached them along
Thanks in advance.
