I'm trying to parallelize parametrized jobs from a Multi-Project one.

The fact is that the configurations of the jobs are the same. When I build my MP jobs the error can occur on a sub-job which is not always the same, it's really hazardous.... There is no logic in it

Did somenone encountered this error too ?
