SOAP to proxy scenarion error An error occurred during the processing of proxy E 00 001 The message can not be processed in plugin mode HTTP

Hi all

My scenario is soap to proxy scenario .while testing using soap to proxy i am getting " An error occurredduring the processing ofproxyE00 001The messagecan not be processedinpluginmodeHTTP:  in sxmb_moni sap pi .

Some times this interface is failing and some time its successfully processing.

While testing with successful xml data also i am getting the same error in sxmb_moni.

I modified the proxy inbound code where passing error message  and still i am getting the same message.

Please suggestion the same  for error solving.

Regards

Ravi.
