I'm having difficulties in migrating modules. It looks like it is behaving inconsistently. When I migrate six modules earlier, one of them failed with the log message reading extraction error and that a HP internal error has occured. Now, when I try six modules, two of them failed with the same message. Just checking if this has been encountered earlier and if there is any explanation to this kind of behaviour.
We see random failures with migrating modules, too. Often, retrying the failed migration immediately will work. Sometimes it takes several retries. We have not been able to identify any pattern to the failures but it is pretty obvious it is a problem in the migration code. We are running 6.0.
