The KB that explains how to fix this is https://support.emc.com/kb/457868
By design there is a 32 snapshot limit. This limit is in vmware not Avamar. If the backup is failing because you have more than 32 snapshots there is a good chance your not following VMWare best practices. See https://kb.vmware.com/kb/1025279
If your seeing a lot of warnings about Too many extra snapshot files in my experience this is fairly common in some versions of vSphere 5.1 and 5.5. In vSphere 6.0 and 6.5 its very rare. I suspect it was a bug that was fixed by VMWare at some point but I don't know the specifics of when.
