I've updated Tor to the newest beta:
Tor v0.2.7.4-rc (git-f55d23e1e66e9b0f) running on Windows 8 [server] with Libevent 2.1.5-beta, OpenSSL 1.0.2d and Zlib 1.2.8.
 
I'm still experiencing errors:
Oct 27 01:22:29.000 [warn] Failure from drain_fd: No error [7521 similar message(s) suppressed in last 7200 seconds]
Oct 27 03:22:31.000 [warn] Failure from drain_fd: No error [7774 similar message(s) suppressed in last 7200 seconds]
Oct 27 05:22:33.000 [warn] Failure from drain_fd: No error [8451 similar message(s) suppressed in last 7200 seconds]
 
Is there something else to try?
 
Thanks,
Brian Walker

Apologies, that’s hidden rather deep, isn’t it?
I’ve logged https://trac.torproject.org/projects/tor/ticket/17209 so we can fix this.

The fix you want is only in 0.2.7.3. I assume we will compile a version for Windows either:
* when 0.2.7.3 becomes stable, or
* when 0.2.7.3 is used by a Tor Browser release.

Alternately, you could compile from source, if you are able to do that.

The closest I could find is this:  https://dist.torproject.org/torbrowser/5.5a3/tor-win32-0.2.7.2-alpha.zip

Looks like the status of the ticket has been updated to Resolved with the comment:
 
"Merged to master; if this helps us find a real bug, that bugfix will be backportable."
 
I'm now on v2.6.10 with Libevent 2.0.21-stable, OpenSSL 1.0.1p and Zlib 1.2.8 on Server 2012 R2 and I'm still seeing the warnings.

As 0.2.6.10 was the stable release 6 weeks ago, it does not have this fix.

The master branch referred to in the ticket is now 0.2.7.3-rc. If you are comfortable using release-candidate code, please try it, otherwise, there should be a 0.2.7.3 stable release soon.
