Hello together,

although the last posting has been already done a while ago, out of respect for
the meticulous work of Eric (and Tim and Wayne) - which was a pleasure to read
for me - I'd like to add an observation I made for the very same strange rsync
behaviour.

I tried to rsync some 225GB of image data (mainly 8 to 12Mpix JPG files) from
my notebook (openSUSE 11.4) over a WLAN (ca. 120MBit raw) to a RaidSonic NAS
(connected to my router with 100Mbit cable, has officially a 1GBit interfacw)
which writes the data to a RAID1 configuration of 3.5" hard drives.
So, no real large files. But a not so fast NAS.
It hung up again and again with the above mentioned message "rsync:
writefd_unbuffered failed to write 4092 bytes [sender..." for different files.

After all the discussion of network matters that I saw from your thread I
thought (as I'm working in my LAN) I could turn of openSUSE's firewall for a
try. And: since that moment everything runs fine! And even fast. rsync doesn't
stall and files arrive properly, independent from size (I also got some larger
files).

Although I'm not able to make a deep analysis as the writers before, I hope
this observation helps one or the other who googles for the error message...
