ICM : 400 error Session timed out

Greetings all,

we have a BSP page, when we try to access through the portal most of the time it works fine , but occasionally we encounter this error 400 Session timed out.

other details of the error ,

error: (-11)

component ICM





This happens suddenly while we are active on the system.

after checking into the system with SMICM transaction I found out that the number of current <i><b>created worker threads</b></i> approaching the maximum limits, but not exceeding it.

when i checked the same transaction when the page was successfully excuted without that error i found out the number of current <i><b>created worker threads</b></i> is fairly away from the maximum limits.

could it be that this is the problem.

the problem here that i don't have the right to just change the maximum and see for myself, so i have to look this up and came up with the solution then go to the right guy and just ask him to do it.

Thanks & Regards

    'What is parameter icm/conn_timeout' value in your system ? The system's Internet Connection Manager(ICM) is configured for 5000ms (Default value). The processing time for the root node exceeds this specified connection time of 50 secs. This results in time out error.

    Please change the value to 50000.

    Please refer the note 774439 - Connection time out for the BSP Application & 737625 - Parameter recommendations for the ICM

      Hi Bala,

      I recommend to read SAP note 705013, I think adjusting the kernel parameters

      rdisp/gui_auto_logout and


      will help.
