PLSRV_OUTBOUND_BINDING taking long time

Hi

My scenario is getting stuck in the pipeline step PLSRV_OUTBOUND_BINDING consuming almost 8 hours,it ran in 4 min a while ago.

The scenario is getting executed successfully but taking lot of time.

In my scenario XI picks a file 0f 40 MB from an FTP location and then should pass on to the proxy.During the execution of message we have observed the size of the file to be of 130 gb in SXMB_MONI,after the successful completion of the message it is back to 40 mb.

Help me in tracing why PLSRV_OUTBOUND_BINDING is consuming such a long time
