500 Connection timed out

[former_member182374]

Hello Experts,

I've a Web Dynpro ABAP application.

When a user clicks a button he runs time intensive function (if I run the function directly from SE37 it takes 90 seconds).

I'm getting a timeout 500 error message (see screenshot).

I read that timeout errors in WDA usually related to ICM but as far as I remember ICM errors contain the word 'ICM' in the error message (c module, error line etc).

Also, I didn't find any log entry in SM21 for the error.

Where can I find the detailed error message?

Regards,

Omri

Solved by changing to icm/keep_alive_timeout from 60 seconds to 300 seconds.

Hi Omri,

It seems like the timeout of the HTTP connections is too low. Contact the basis team and ask them to increase the timeout of HTTP connections.

Hi Manish Kumar,

Do you know the exact name of the profile parameter?

Hi Omri,

To ensure that we are talking about the right timeout, do you observe any relevant error logged in the ICM trace (dev_icm)? For a time-consuming applicaiton, I would suspect the ICM processing timeout (PROCTIMEOUT in icm/server_port).

The so-called connection timeout (icm/conn_timeout) specifies the timeout for connection establishment to a remote server. This has something to do with the network performance of connection establishment and has nothing to do with the application intensiveness.

Best regards,

Hi Jun,

As far as I know ICM errors looks like this:

Error: -5

Version 7010

Component: ICM

Connection to partner  timed out after 60s

In my case only  "500 Connection timed out" is displayed on screen.

Hi Omri,

That means, it is the ICM processing timeout. Please increase the ICM processing timeout (PROCTIMEOUT as mentioned earlier) accordingly and restart the server/ICM to accommodate the time intensive applications.

Best regards,
