NullPointerException at org.apache.axis.message.SOAPBody.addBodyElement(SOAPBody.java:167)

[Dennis Kieselhorst <ma...@dekies.de>]

Hello,

I have some problems with my webservice application when there is a high
request count. Found the following exception in the logs:

18:16:11 ERROR org.apache.axis.SOAPPart Exception:

The client gets HTTP 503 error. After rebooting the tomcat everything is
fine.

Is this a bug or just a subsequent fault?

Environment: Axis 1.4, Tomcat 5.5.20, SunOS 5.8

Dennis
