>             Project: Ivy
>          Issue Type: Bug

> We're getting occasional build failures where Ivy seems to be trying to read only partially-complete
XML files from the cache.
> This happens only on our Hudson box, when it's running ~4-5 builds at a time, so my theory
is that the separate Ivy processes are not blocking each other from reading incomplete files--just
restarting a job makes it work the second time, so it's a very transient error.
> Stack trace is below.
> Does it seem likely that RetrieveEngine's determineArtifactsToCopy is missing some locking/ordination
around line 286/288 where it uses cacheManager to get a file and then parse it?
> java.lang.RuntimeException: problem during retrieve of bizo.com#b360-bizads-processes:
