Hi,
Today I have an issue when trying to issue a COPY for one object I
have in RGW. It only happens for this object (at least that I noticed
and I did 1000's of COPYs in this batch) and I can do a GET of this
object just fine.
The stack trace :

NOTE: a copy of the executable, or `objdump -rdS <executable>` is
needed to interpret this.

The actual file content is in :
default.440489.58258__multipart_5ae1b8cb8a2bdc3c2d7e1868b60d76abea2536f4604d6d312df95b719470fb3b/render-image.8rSDD8MVD1KIXDTQDsf3g6b71dqADP_.1
and is correct (if I fetch the object with rados, it's all there).
Cheers,
Sylvain
