SAP PI - REST receiver adapter - Content-Length > 900 - request hangs

Hi colleagues,

I've got very strange situation on PI 7.5 SP6 with SAP ERP - PI - REST(JSON) service scenario.

If I'm using small amount of data in request - the call goes fine till the external system and back, but if I send more than ~1Kb (according to Content-Length header parameter) - request hangs and stops after time-out.

XPI Inspector shows (content skipped):

1) Successfull call:

HTTP_CLIENT : 129 REQUEST:

2) Call hangs on time-out:

I spent a lot of time changing content, timeouts - nothing.

And interesting - if I set Content-Length manually via Header tab in REST adapter settings to more than 1000 - the request hangs without taking into account real size of the request body.

Could you please advise - what is the root cause of this?
