Apache Soap 2.2 Web Service stops responding after continuously r unning for 2 weeks

["Ding, Chengmin" <Ch...@tfn.com>]

Hi,All,
Today we found out our Web Service stopped responding after successfully
running for 2 weeks. No error message was displayed in the tomcat console or
any log files. The VB client just returns 
ErrorNumber: 5400 
ErrorDescription: Application or Object defined Error

Then we ran the addressbook sample and mime sample, both worked fine. But
when we ran the testProvider sample, we encountered the same problem-- The
service never returned and the java client just hang there. 

We want to know whether anyone has encountered a similar problem after
running the webservice for   several weeks? Is it a rule of thumb to always
restart the web service every couple of weeks? (just like NT :))

BTW, can we run the Apache Web Service without a user logon? Now we have to
lock the Server for Apache Soap/tomcat to run. We are using Tomcat 3.3 and
Windows 2000 Server.

Thanks in advance.
