Zack Shoylev commented on JCLOUDS-1064:
---------------------------------------
Thanks! This is very helpful. This shows that the request for uploading one of
the parts was failed by the swift service after some retries. Now, in this
case, this didn't seem to result in a NPE? Was something different?
As for the 502 itself. Smaller parts and more retries / more backoff between
retries might help, as you might be overloading your swift provider.
