Receiving error "Can't get a 384 bytes share memory!" during rsync

[larsl]

I'm setting up a backup script which is supposed to run on a QNAP NAS from where it SSHs into another server and retrieves some backups via rsync.

This is what I'm running:

rsync -autzq -e "ssh -p7434" backupuserätexamplecom:/media/backup/database/ /share/example_backups/databasebackups/

I had to change the "SSH user at host" thing because the forum software thought I'm posting a weblink.

It seems the rsync actually runs fine. However, it still throws this error twice:

rsync: Can't get a 384 bytes share memory! (-13)\#012: Unknown error 4294967283 (-13)

When I google it, it seems that error is not exactly common. Does anyone have an idea what could be causing this? (Again, the system it's running on is a embedded linux on a NAS)

Is rsync running on the Qnap NAS, or on the host? Most NAS devices pretty much have minimal memory, so if rsync is running on the NAS, this may not be unexpected.
