That is too soon to tell. The user needs to provide more details what
happens, for example if there is any exceptions or other kind of
messages form the logs etc.

And if he can put together a small sample that reproduces the issue.

And as always he should tell us which Camel version and Spring version
he uses. And what OS and JDK is sometimes also good information to
know. And he should try upgrading to a newer release as well.
