macos – NFS mounts that regulary disconnect

MacOS 15

I’ve a couple of NFS mounts on my Mac which might be exported from a Synology NAS (beneath DSM 6.2.4). They’re configured within the automount information. I’ve as an example in /and so on/auto_nfs2:

nonas.applications          -fstype=nfs,noatime,rw,nfc nfs://synonas.native:/volume1/Applications nonas.stockage          -fstype=nfs,noatime,r,nfc nfs://synonas.native:/volume2/Stockage nonas.internet               -fstype=nfs,noatime,rw,nfc nfs://synonas.native:/volume1/internet  nonas.houses             -fstype=nfs,noatime,r,nfc nfs://synonas.native:/var/companies/houses 

and in /and so on/auto_master

/mnt/nfs                auto_nfs /Customers/Shared/mnt/nfs   auto_nfs2 

To date so good, the shares are mounted on startup, and accessible.

However repeatedly, virtually as soon as a day, they disconnect. Typically a few of them, typically all of them. The mount factors merely disappear…

• sudo automount -vc would not assist
• rebooting the NAS would not assist (even with a sudo automount -vc after reboot)
• rebooting the Mac does assist, the mounts are again

I attempted configuring them in /and so on/fstab as a substitute of /and so on/auto_nfs2, but it surely’s similar (possibly even worse I believe, it occurs extra regularly). Earlier than that I had an outdated Mac beneath 10.13, and the mounts have been far more secure (deconnections might occur, but it surely was a lot much less frequent).

Any thought about what it’s occurring or the place to analyze?
