Hello Sateesh,

Maybe this document will help:

How To Investigate Timeouts in Synchronous Scenarios - http://scn.sap.com/docs/DOC-16238

2.2 Timeout Calling the Adapter Framework, section 2.2.2 - HTTP 401 - Authentication Failure

Quoting the article: ICM time out due to less connection pool during high load. During high load, user authentication failure occurs at ABAP UME.

The proposed solution from the document is:

Check these parameters in NWA / VA:
ume.r3.connection.master.poolmaxsize
ume.r3.connection.master.poolmaxwait
Default Max. Connections: 20
Default Max. Wait Time: 10.000 ms
Increase parameters until problem disappears: for example,
Max. Connections=50, Max. Wait Time=60000

Hope this helps,

Mark

Hello Mark,

I follow up this note 821026 and changed to parameters and rebooted like below according to my system PI 7.31

Max connections:  50

Pool size: 25

Max wait time in ms : 60,000

Is this right configuration?

but still I am getting same Authorized error on
