RE: HTTP 502 Proxy Error in Axis 1.3

I would hazard a guess that it is an infrastructure problem
(request/response routing, IP address changing), since your web services
do work some of the time.
You might want to get your production support (network engineers) onto
it.

        Hi,

         

        We have a webservice which is using Axis 1.3.

         

        There are some clients using our webservices.  One of the
clients reported that he is getting a HTTP 502 Proxy Error
intermittently when accessing our webservices.

         

        Does anyone face this problem before or know why this is
occurring?  Is there any solution for this issue?

         

        Here is the stack trace of the error.
