dcache version 7.2-snapshot (84b45e6f11)

[paulmillar]

Just to mention that this stack-trace looks incomplete. Shouldn't there be something within dCache throwing this exception?

The error message is coming from Poolmanager (RequestContainerV5).

So, it looks like this is being transported back to WebDAV door as IAE, which is being re-thrown as a WebDAV exception.
