Repeated segmentation faults in NFS-Ganesha ganesha.nfsd processes
Issue
The NFS-Ganesha processes have started to repeatedly crash with segmentation faults. Cluster failover happens properly but the second member of the NFS cluster subsequently fails as well, leaving the luster without any active NFS servers.
All the cores seem to have crashed at the same place (though the code paths/bt are different) -
Program terminated with signal 11, Segmentation fault.
