Hi everyone,

I'm running a small test setup of swift with one proxy+storage and one
storage instance.

The setup seems to be running well for small objects. I'm able to create
and upload them successfully using swift cli tool, but for large
objects(>1G), I get error of "503 service unavailable"(on swift cli) after
a long wait.

I dig into logs and found that none of the replicator services are running.
All of them give the following error(array index out of range)

Additionally, while the transfer of a big file was going on(4GB), I got the
following error in logs.

proxy-server ERROR with Object server 10.0.1.1:6000/sdb1 re: Trying to

Any suggestions?
