I can't replicate it the error on demand. I've used the exact servers and
files that caused the issue in my testing and I cannot get it to repeat on
demand. The issue, however, still occurs daily. My analysis of the log
files from rsync do not yield any definitive clues on the issue either (e.g.
specific load, affecting multiple rsync proceses at the same time,
etc...none of these things are happening). Other posts on "resource
temporarily unavailable" indicates a lack of threads or memory and kernel
modifications address it. Memory is not the issue here per my monitoring.
Threads do not seem to make sense since the only time the error ever occurs
is when the posix_fallocate function is used in the rsync.

No OS limitations...the problem only occurred when we moved to more recent
builds of 1.7. I also think it is related to the build we are using, Cygwin
1.7.0-28, since when I compiled the exact same rsync build/patch/code under
a previous version I did not have the problem (e.g. build date 7/19/08).

No OS restrictions...been using the same configuration for two years without
this issue although clearly not on 1.7 with posix_fallocate for that entire
time.
