Warnings during recover from S3 gateway

Hi all,

I am doing a test for a disaster recovery process and while restoring from
s3 gateway. It seems to work ok but I see a few of those warnings:

[2012-08-27 22:03:33,176][WARN ][index.gateway.s3 ] [Fault Zone]
[myindex][3] failed to read commit point [commit-35ta]
java.io.IOException: No commit point data

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603)
at java.lang.Thread.run(Thread.java:679)

Is this normal or does it imply something about the integrity of my backup?
I do see recovery completed messages at the end of the process for all
nodes.

thanks in advance!
