IDOC transfer between 2 systems => freeze of the sender system

[Former Member]

Hello,

We are facing to a strange problem in our production system.

We create a RFC connection from our production to the development system to transfer master data for finances. In our sender system, we create a partner type to export IDOC with message type GLMAST.

When we transfer 78 IDOCs from our production system, a lot of RFC connections are created in development system for input (more than 140). And in our production system, the system will freeze. It's impossible to open a new connection or to do something in the opened screen. The only solution is to stop SAP directly by admin on OS system (AS400), and restart it.

When we do the same in the DEV between to client and by sending 600 IDOCs, no problem appears.

The paramaters of system seems to be the same between production & development.

The same problem appears from DEV to PRD.

Any idea ?

Thanks & regards

Hi Bruno,

You may want to review the settings for RZ12 in DEV and setup a server group. In the server group, you can limit the number of incoming RFC connections. Generally, you can set a percentage for the number of work processes used and how many should remain free for other tasks.

Hope that helps.

Hello Bruno,

1). How many number of Dialog work Process available in Production system ?

In Dev, there might be less user's with more Dialog process, so there might not be issue in Dev. However in production there could be more user's and same number or less Dia work process.

Try to increase the number of Dialog work process and try again

2). if production is in Hang status, did you check in OS level to see how work process looks like ?

If you increase number of Dialog work process, it should fix the issue.

Thanks,

Hello Arjun,

Thanks for your answer.

Currently we have only Finances team which work in production system, so only 10 users.

1) In DEV & PRD, I have only 10 dialog work process. But when I look SM50, on dev before the system starts to freeze, I have only 2 dialog work process running. so, it's not a problem link to this.

2) in OS level we saw the system working fine ! but we found in the trace (accessible thru ST11 normally) some lock apprently and in production, some dump are created with an error SWF_RUN / MESSAGE_TYPE_X

Ok, What is the value of parameter enque/table_size in your Instance profile? 4096 ? Increase like below

enque/table_size = 60000 , restart the Application and try again.
