Good afternoon, Last week in the middle of a transmission the wowza service crashed, analyzing logs and graphs I found no problem related to processing or memory. But I found this mistake that was at the same time of the fall, but could not interpret, can help me?

“ERROR server comment 2019-11-29 18:34:33 - - - - - 3258.065 - - - - - - - - class com.wowza.wms.rest.server.publishers.PublisherConfig3.p ost : java.lang.NullPointerException|at com.wowza.wms.rest.server.publishers.PublishersConfig3.addPublisher(Unknown Source)|at com.wowza.wms.rest.server.publishers.PublisherConfig3.saveNewObject(Unknown Source)|at com.wowza.wms.rest.Conf igBase.post(Unknown Source)|at com.wowza.wms.rest.server.publishers.PublishersConfig3.post(Unknown Source)|at org.restlet.resource.ServerResource.doHandle(ServerResource.java:454)|”
