I am having the same problem with Backup Exec 2012, and I am assuming that everyone else is probably receiving the same problem. The problem with the Backup Exec is that the services crashes each time you try to establish a connection.
Each time you install the Linux agent on the server everything is working fine, you can start and stop the services at any given monet; however, once you add the server to the Backup and establish a trust, the Agent crashes. From what I have seen and tested it only happens with the Unbreakable Enterprise Kernel (uek) and not with the EL kernel.
Unfortunately, Symantec requests that you booth the server in the el kernel version, but Oracle does not recommend this.....so it is a see-saw battle.
The problem is the kernel version "uek".......I am hoping that the Backup Exec SP2 would solve this situation or sometype of patch. Has anyone else seen this?
