rsync crashing TCP stack

[campigenus]

OK, a bit of background first ...

For the last few months I have used simple rsync commands to sync a local directory to a remote machine:
"rsync -avz --delete /mnt/local /mnt/remote"

/mnt/remote is mounted via:
"sshfs -o allow_other root@remotemachine.no-ip.com:/mnt/shared /mnt/remote"

This has worked wonderfully and all was well. As of a couple days ago the rsync command starts OK and then a few minutes later the machine it's running on drops of the network. It still replies to pings, but that's all. No ssh, no VNC, no SMB access. Nothing. Nothing short of a power cycle brings it back to live.

I don't remember any recent updates to the apps used, and it's really miffing me.

Oh yeah, this morning I added a directory with a few thousand files locally, and I was able to do a "cp -a /mnt/local/NewDirectory /mnt/remote/NewDirectory" so the link to the remote site is OK.

Any ideas?

Checked any logs for crashes?

Wild guess - maybe the compression is taxing things too much with all the new files? Try without it.

I happened to me at work when we had LOTS of files to transfer...
rsync seemed to keep a list of files to transfer, and that list ended up to eat all the memory...
could you watch the memory usage after running the command?

syncable or not, changed or not, do you have lots of source files and directories?
you could try with a subdirectory
