rsync 3.2.3 keeps crashing on Mac mini M1

Question

Trying to use rsync on a Mac mini M1 to backup from an external hard drive(formatted as APFS) to a NAS (shared as smb/cifs). I've tried a number of rsync commands but this was the most recent

rsync -avv --delete --info=progress2 /Volumes/FranBackup_6TB/FranArchives/Frans_Files /Volumes/FranArchives/

It starts running fine but after a while, maybe an hour or so it completely crashes the system and my Mac reboots. I've tried the cp command and that doesn't seem to crash. Below is the error message received after rebooting.

edit I failed to mention I had installed rsync version 3.2.3 via brew.

** Stackshot Succeeded ** Bytes Traced 332209 (Uncompressed 819888) **

Lot of variables here. Not sure if it's related to rsync, or Big Sur, or M1 chip or the smb/cifs share etc. Any ideas? Seems pretty simple what I'm trying to do. Just back up my external drive to my NAS.

I've filed a bug with the Samba team (maintainer of rsync) and referenced this post bugzilla.samba.org/show_bug.cgi?id=14962 — Arjun Mehta, Jan 27, 2022 at 16:28

Reverting back to the default macOS default version of rsync (2.6.9) resolved the issue.

Which version and how did you install it, had the problems and that information has to be in the question.

May 23, 2021 at 15:03
@mmmmmm I installed it via brew and version 3.2.3 was installed. I followed the steps outlined in this guide. dev.to/al5ina5/…

Same issue exists on Monterey! Need to use the old 2.6.9 version of rsync.

I wish I found this post earlier. I thought there was something wrong with my computer, so I reinstalled the whole system.

The rsync that Apple includes in Big Sur is rsync version 2.6.9 protocol version 29. It's from circa 2006.

The current version of rsync is rsync version 3.2.3 protocol version 31.

You can install it from Homebrew or MacPorts or try building it from source, if you want.

But it's no surprise that a 15-year-old tool is having issues. I assume there is some sort of licensing that prevents Apple from including a more up-to-date version of rsync with macOS.

I would suggest installing a new version and trying again.

Thanks- forgot to mention that I have updated to rsync version 3.2.3 but still get this error.

Even though the OP forgot to mention they'd already upgraded rsync, nonetheless, this is a good answer for anyone else landing here trying to troubleshoot an issue with rysnc, as upgrading older utilities is always a good part of the troubleshooting process. +1

@fpolig01, Did you have the same issue with the macOS default version of rsync as well?
– user3439894

Yes, I was going to suggest the opposite: try the MacOS tool, rather than the homebrew one.

Actually it is a big surprise that a 15-year-old tool were having these issues. A user-space program generating a kernel panic is a surprise in itself, but it would have been less of a surprise with a new, "unproven" tool rather than an old, tried-and-tested tool.

This issue still exists, on the default shipping version of rsync, on Monterey 12.2. I’ve also found that the issue surfaces using ArqBackup targeting an SMB share for cloud backup.

What happens for me before the total system crash, is that the network link itself actually crashes and shows as offline, prior to securityd segfaulting, and then a barrage of keychain password prompts. This culminates in an unexpected total system reset/restart.

In my case, I’ve completely uninstalled homebrew, and the issue still persists. Happens on both an M1 Mac Mini and an M1 MacBook Pro. Hoping to do some testing on an Intel MacBook Pro this weekend.

I realize it doesn’t answer it, but it does add a data point along with other testing that has been done. I’ve opened a feedback with Apple regarding this problem given I have it happening on multiple systems.

Just a heads up that I’ve found that MacOS 12.3 has fixed the stability issues seen with SMB mounts.

I have Macbook M1 Pro (Mac OS Monterey 12.4), and switching from default rsync to brew rsync 3.2.4_1 worked for me. I gave the command,

brew install rsync

and then located the location of the rsync binary installed (which was /opt/homebrew/Cellar/rsync/3.2.4_1/bin/rsync in my case) and used the same to download the files, and it worked perfectly.

The question says that they had installed rsync via brew - soi how does this answer the question?

This answer seems to be pointless. The only difference from the OP's question is that the OP installed verson 3.2.3, also via brew.

Upgrading to 3.2.4 seems a good step and then possibly opening an issue with the maintainer if there is none and you have a repeatable report
