Too many loopback session id's in SMGW transaction

[Former Member]

Hi All,

From SMGW transaction I am able to see too many loopback (127.0.01) session ids existing in the system.

• 107 system(s) logged on *** showing from this more than 50 session are loopback. I am not able to find the reason.

How to check and how to reduce this session.

Thanks in advance

Hello Pravin,

Some of those connections can be due to JCo connections between your Java instance to your ABAP instance. The JCo will always connect to the gateway and by the ABAP by the gateway.

Other entries could be by internal RFCs for this system that are pointing to the loopback.

If those connections won`t get closed, I strongly recommend you to read SAP Note 568271 that talks about the lifetime of an Rfc, which are the most part of the connections that you will see on the gateway.

Cheers,

Maurício
