I'm using VMWare ESXi with a datastore on a Synology NAS (via NFS), and occasionally the ESXi box disconnects from the NAS for a couple of minutes, and the virtual machines are unresponsive. Looking at the VMWare logs points to the connection dropping. Looking at the Synology logs by doing (?diagnose=debug) shows at the same sort of time that the VMWare box loses connection, I get this message:
Mar 6 19:44:15 afpd[3754]: [afp_dsi.c:366-E] afp_alarm: child timed out, entering disconnected state
Mar 7 09:40:22 afpd[13570]: [afp_dsi.c:366-E] afp_alarm: child timed out, entering disconnected state
While I don't have the VMware logs for the 19:44 incident, I do have logs for the 09:40:22 incident:

Does anyone have any ideas? I'm at a loose end here?
Thanks
