Custom Process - Error while saving more than one contact

Content

Hi,

I have a custom process for incident that, sometimes, it has to create several contacts. The code works for the first contact but it throws an error message while trying saving the second one saying:

"Uncaught exception ´RightNow\Connect\v1_2\ConnectAPIErrorFatal' with message 'Cannot save/create: Contact: Unknown fatal error while saving/creating Contact'"

The line that throws the error is the one with $Contact->save();

Cannot I create more than one contact from a custom process? 

Thanks.
