500 Timeout Error

Hi Experts,

We are getting "500 Time Out" error in sender Http client.Our scenario is synchronous Http to RFC.

In sxmb_moni,Integration engine stops at technical routing step.No call adapter step is visible.

While looking into this problem we found that RFC got successfully executed in target R/3 system and we assume that problem lies while sending the RFC's response back to HTTP client via PI server

Adapter engine AuditLog mesage is pasted below for your reference:
