[NFS-Ganesha-Support] questions about stability of nfs-ganesha versions and PROXY FSAL

I'm having stability problems with nfs-ganesha 2.8 and PROXY FSAL on CentOS 7. I haven't yet tried nfs-ganesha 3.0 but I could probably quickly and easily move to that if there is an advantage in doing so. Before I spend time switching from 2.8 to 3.0, can anyone tell me whether either of these versions of nfs-ganesha is considered to be more stable than the other? centos-release-nfs-ganesha28.noarch : NFS-Ganesha 2.8 packages from the CentOS : Storage SIG repository centos-release-nfs-ganesha30.noarch : NFS-Ganesha 3.0 packages from the CentOS : Storage SIG repository What about PROXY FSAL in either of these versions - is one or the other known to be more stable? Is there a more robust version of nfs-ganesha and PROXY FSAL that I should consider trying instead? Thanks, Todd
