status code 25 on rman backups

[BackupJ]

SunOS netback01 5.10 Generic_137111-07 sun4u sparc SUNW,SPARC-Enterprise
using version 6.5.3 for rman backups. 

I am getting a repeat, intermittent failure of status code 25.  The only error I can pinpoint in the logs is :

I am confused how this could only happen every couple of backup attempts though.

Any thoughts would be appreciated

Thanks

This is a name resolution problem and probable specifically reverse lookup.
next thing to check is if the script does a su - oracle

Hi Stumpr,

the script does an su - oracle...  It seems everything is resolving & the permissions are correct.  Unless I am not checking something correctly

Hi BackupJ,

By all means, this is a network issue.

Here are a few things to check

How many interfaces do you have on client?
What is the OS on client?
Do you have REQUIRED_INTERFACE set?
Is there a firewall between the master/media server and client?
Are the hosts file updated properly?
