Hi All,

I see the following trace in my SAP Gateway(smgw transaction) trace.

Using the <sid>adm userid at UNIX level I am able to read the dev_rd trace, so there is no OS authentication issue. Also I am using an id with SAP_ALL so there is no authorization issue.

Has anyone faced this issue earlier ?
