TDP Domino Backup issue

[balaji419]

Recently our full domino database server backup session is running too long, and in the middle of the backups we are getting below errors.

What could be the cause of this error? Is this related to network issue? Have any one faced this type of issue before?

Have you checked the health of your network, or the network in generally between the TSM Server and Domino servers?

Thanks moon-buddy for your reply. we restarted the windows domino server, and after that TDP Domino Full backups seems to run fine. Will update how is it working in the future.

I am facing same issues and updated the TSM domino client to 5.5.3. But observed same issues again.

I checked ping and tracert details but not found any errors.
