Hi there, Whole (macOS) system is crashing when transferring a large number of files from Mac to NAS via rsync. Running the below command on a directory with thousands of images (~5MB each) the transfer speed eventually slows down, the system gets choppy, freezes and then eventually the entire computer reboots. rsync -va --update --info=progress2 /Volumes/Source/folder /Volumes/Destination/folder I found this reported here as well: https://apple.stackexchange.com/questions/421007/rsync-3-2-3-keeps-crashing-on-mac-mini-m1# I experienced this on a M1 Mac mini running macOS Monterey. The stackexchange post is running Big Sur. rsync 3.2.3 was installed via homebrew (brew install rsync) so it may be possible this is a homebrew distribution/compile problem. The only solution for me was to downgrade back to use the included rsync in macOS (rsync version 2.6.9 protocol version 29)
This is probably the same kernel memory leak I documented here: https://bombich.com/kb/ccc6/macos-monterey-known-issues#smb_panics You can confirm whether it's the same issue by looking for zone_map_exhaustion in the system log. e.g.: - Start your rsync task - Run `log --stream | grep zone_map_exhaustion` in a Terminal window - Run `sudo zprint -d kext.kalloc.32768` in another Terminal window Also watch memory pressure in Activity Monitor. I saw a gradual and steady increase, although it never got to a "warning" level before memoryd started killing things. If that's what you're seeing, it's not an rsync bug, it's a bug in macOS.
