Marianne thanks by the way , you have always helped me and I'm so thankful ., you and all the other members are really a true human and true engineer cause you help people without any expectation.
today I could solve this issue , by reinstalling the agent , changing the backup path ( I presented another LUN from SAN Storage ).
There is never a single common problem underlying status 41. The status 41 can be caused by a very wide range of situations. My advice would be to check that all elements of the network stack and network path do NOT have any strange custom configuration.
.
For example, I post this here purely as an example of how strange network configuration settings can cause strange networking errors for networking applications:

...i.e. I am not trying to suggest that your problem is this, merely to demonstrate an example of a strange configuration setting having strange results.
.
However, having said all that, one of the most common usual culprits with networking errors is "TCP keepalive". I'll let you do some searching on that topic. Remember, "keepalive" is a feature at all points along the network path... source, carrier, target. i.e. you must check the keepalive at all network contact points, which means: client, switch, media, switch, storage, switch, master.
There are four OracleLinux netbackup clients in the environment, two of them have this issue, so I think TCP Keepalive must be configured correctly otherwise those two must have the problem.
Hello,
Did you try to enable logs as suggested by Marianne ?
sdo 's post is interesting, it's obvious the error is about the timeout, which is 30 minutes, which means that media server was waiting for all that time and didn't receive any data.. so, what you need to do is enable logs and look at it closely on what causes this delay.. because I believe even if you increase TO to 3600 you will get an error after 1 hour.. so you need to dig on this.
also, you said this issue concerns 2/4 oracle clients, so you have to look at which kind of data & how big it is are being backed up by these failing clients.
Good luck
