The media agent goes offline after a while. Restarting the services on the media agent resolves the problem temporarily, but it goes offline again after some time. All server groups are in the same VLAN.
We recently transitioned to this system, using Exagrid84 as the backup storage. I have two media agents, one virtual and the other physical (named comm-media and comm-media1, respectively). This setup has been working smoothly for about 2 months. In an effort to reduce backup times, I prepared another virtual media agent and added it to Commvault. However, when I shared it as a third media agent to the Exagrid84 mount paths, both the paths and the comm-media agent went offline.
While installing the Commvault agent on the third virtual machine, despite having .NET 4.7 on a Windows Server 2016, it prompted an error saying it should be version 3.5. Upon checking the working comm-media server, I noticed it wasn't installed, so I installed .NET 3.5 on both machines. Later, suspecting this could be the source of the problem, I removed these features.
After some time into the backup processes, I encounter the following error. However, there doesn't seem to be any issue with communication between the machines and Exagrid through the network, as I can perform file transfer tests successfully between them via Windows Server.
Actions taken to resolve the issue:
Temporarily disabled the third machine.
Updated the media agents.
Restarted services and servers.
Despite these efforts, the comm-media agent still goes offline after a while, whether backups are initiated or not. I am unable to find a solution to this issue. Urgent assistance is needed.
