I am running Tomcat 6.0.20 on Solaris 10 10/09 s10x_u8wos_08a X86 with spring-ws-1.5.9.

About once a month, under normai load, my webservice stops working (serves up the wsdl contract, but the endpoint seems to just stop responding to requests). The problem starts with the following error being sent to Catalina.out:

SEVERE: SAAJ0533: Cannot create message: incorrect content-type for SOAP version. Got application/soap+xml, but expected text/xml
Dec 15, 2010 10:41:51 AM com.sun.xml.internal.messaging.saaj.soap.MessageIm pl init


Has anyone seen anything like this, or have ideas what is happening?

Thanks in advance.
