This error happens during a small file transfer (gif image) and after 75% of a 165G rsync job (the building file list portion is complete.) Most solutions I saw were related to not having enough RAM or running out of disk space. Check out the machine specs below the error.

anyone seen this?
Not an rsync problem. This is a kernel issue.
You seem to be out of ZONE_DMA memory. I don't know whether you should be reporting this to RH or Veritas or IBM but when you do be sure to send them /proc/slabinfo from the moment of error.
One thing you might try is booting with mem=900M Running with more than 900M < n < 1G memory on 2.4 kernels is problematic.
I am experiencing this same problem with rsync 2.5.6 and 2.5.7. The difference for me is I am running Solaris 8, not Linux. I am using the same procedure to rsync ten different servers to a shared NFS storage, but one of those ten servers comes up with the following error (very similar to above).
rsync error: timeout in data send/receive (code 30) at io.c(103)
rsync: writefd_unbuffered failed to write 69 bytes: phase "unknown": Broken pipe
rsync error: error in rsync protocol data stream (code 12) at io.c(515)
Just wanted to mention it was not Linux specific.
