XI Server Malfunction:Error in Receiver Adapter

Question

Hi all,
We are facing a problem with the J2EE Engine of our XI server.No scenario is working,as the receiver adapter is not being called.
For every scenario,the sender adapter works fine,but I get the following error on the receiver side:
<b>'HTTP response contains status code 503 with the description Service Unavailable'.</b>
e.g. in a simple file-to-file scenario,the sender-side file gets picked up but on the receiver-side file I get the above error.
Previously working scenarios are also not working.
The error is in the 'Call  Adapter' part of the pipeline and I am reproducing the error (shown in sxmb_moni), for your convenience:
<!--  Call Adapter

The problem is intermittent.The server does work,but only ocassionally.
Your help would be greatly welcome,as we are unable to proceed.
Thanks in advance.
