Stefan,

I'm very happy to try and debug what is going on here, because good
support for large directories are very important to me. 

Was it in a 100% CPU loop?

Can you get a gdb backtrace from where it seems to be stuck or spinning?

Have you tried Samba master or v4-0-test? 

We know there are still some issues in our replication code, but we are
working on them when we can get reproducible test cases. 

Thanks,

Andrew Bartlett
