Siril Suddenly Developed fatal issues stacking from a NAS

Software Siril
1

Siril has stopped working for my use case and I need help fixing it. This is the end of a long line of tech problems that I think will take years off my life, so forgive me if I’m frustrated.

MacOS: Sequoia 15.6.1 (24G90)
Siril: 1.2.6 AND 1.4.0 Beta3

I shoot astrophotography on my roof and I have my laptop set up to record fits images directly onto my NAS over Ethernet. In general, this is great, super convenient and when I first set it up it worked flawlessly for about 6 months. I also stack and edit the photos directly off the NAS on both my windows machine and my macbook in siril. This also worked flawlessly for about 6 months. My Windows computer recently committed seppuku for the 4th time this year (the aforementioned long line of tech problems), leaving me with only my significantly slower MacBook (my work laptop) to stack with. Which would be acceptable if not amazing, except that simultaneously siril stopped being able to stack off of my NAS despite doing it flawlessly the last 6 months.

What happens is I select all my files, hit run, it opens a batch, processes them and then when it goes to save them, everything freezes, the program eventually errors out and tells me it couldn’t find any of the subsequent files after that first batch. That’s odd, because I was just looking at the files in the sequence, they were fine, why can’t they be found? BECAUSE SIRIL DISCONNECTED MY NAS. It does this reliably nearly every time now, it errors, then completely disconnects my nas from my computer, and then says its not connected to the storage volume anymore. I then have to go click on the nas in my network in finder, open it up again, and then I can see all my files. It’s only not done this a spare few times where it did stack, just exceedingly slowly. I checked my NAS, it wasn’t struggling or stuttering at all, and for normal file transfers it seems to be working pretty much normally (I have had some minor issues, it could be the NAS I’m not ruling it out, but siril is behaving much more erratically than the NAS).

Siril has mostly still worked for stacking local pictures, although with some issues and glitches that I don’t think I had before, as well as some complaints about files not being readable (possibly caused when it disconnected the storage from my computer in the middle of creating them), but for various reasons I really cannot put all of my pictures on local storage to stack them, it just isn’t practical.

I tried everything I could think of, restarting both devices, deleting and reinstalling siril, upgrading my nas’s ram, installing both the newest and then an older version of siril to check if it was an update that broke it, doing it over wifi over Ethernet, connected to different Ethernet ports. Nothing has fixed this.

Has anyone else had these issues, and more importantly can anyone help solve these issues?

I’d better warn you, I have no experience with NAS. However, since problem never happened before with siril. And now that it happens all the time, regardless of the version, I’m tempted to think that the problem isn’t with Siril but with the NAS? Or the Mac?

I do this and had to fight a bit with macOS and it’s samba implementation. What helped in the end was : this Reddit discussion : https://www.reddit.com/r/MacOS/comments/13vmx53/been_having_consistent_smb_issues_for_ages_only/

More exactly I inspired myself from this part:
open Terminal, type sudo su, enter your password and press return, then copy/paste the entire text below:

rm /private/etc/nsmb.conf; echo “[default]” >> /etc/nsmb.conf; echo “signing_required=no” >> /etc/nsmb.conf; echo “streams=yes” >> /etc/nsmb.conf; echo “notify_off=yes” >> /etc/nsmb.conf; echo “port445=no_netbios” >> /etc/nsmb.conf; echo “unix extensions = no” >> /etc/nsmb.conf; echo “veto files=/._*/.DS_Store/“ >> /etc/nsmb.conf; echo “protocol_vers_map=6” >> /etc/nsmb.conf; echo “mc_prefer_wired=yes” >> /etc/nsmb.conf; defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool TRUE; exit

I did not blindly modified all the settings, but checked what was on my system already, and added or changed what was different one by one until it worked. Now it’s (mostly) working stable, there are still rare occasional glitches…

wait am I copy pasting the entire paragraph into the terminal or am I entering the commands one by one? You kinda told me to do both things. How do I check what the current settings are if I am going one by one, or is that what the paragraph does?

I tried this It did not fix the problem, perhaps I did something wrong, but there is now a nsmb.conf file says the things the command tells it to say.

Have you also restarted?

Also make sure you are not using the default configuration file.

The first step there is to
rm /private/etc/nsmb.conf

I would recommend to rename it, not remove it and maybe check it against the one you created to see what is different.

Future macOS updates might put it back in place and it will be easier for you to repair it if you know what the changes were…

Look also here, as it says some things have to be changed also on server side…
