Connections sporadically reset between CXF client and gSoap endpoint

Issue

• I'm using JBossWS-CXF as a web service client and gSoap as an endpoint, and every so often my connections are being dropped/reset. For example:

Caused by: javax.xml.ws.soap.SOAPFaultException: Unmarshalling Error: ParseError at [row,col]:[2,4181]
Message: Connection reset

    with linked exception:
