SAPGUI connection WSAECONNABORTED with niping

[sebastian_hockmann2]

Hello.

we are experiencing a lot of SAPGUI connection aborts with Error WSAECONNABORTED.

I had run the command niping with the following parameters:

niping -c -H pja.sap.jenoptik.corp -S 3218 -O -P -L 1000

It breaks after 66 loops. The last one has always a very high reponse time in comparison

with all other pings before. You can see it the screenshots.

So my question is if this behaviour is quite "normal" or does it indicate a serious network issue ?

Must the niping command run without any errors ?

And if so, how can we interpreting the results and aborts ?

Thanks for your hints!

BR,

Sebastian

Hello.

in SAPGUI trace sapni.trc we can some entries like this.

TM_LAYER TmRead (0) >>

NiIRead: hdl 1 received incomplete data (rcd=3468,pnd=5620,pac=2)

NiIRead: hdl 1 recv would block (errno=EAGAIN)

NiIPeek: peek successful for hdl 1 (r)

NiIRead: hdl 1 received data (rcd=9088,pac=3,MESG_IO)

Adresse   Offset  Data from Application Server

The wireshark log shows some TCP retransmissions in this time window.

Any ideas what cause can be responsible for that ?

BR,
Sebastian

Hello Sebastian,

I believe that you have already gathered more than enough evidence that there is an issue at your network .

Hello.

we are still investigating on this. At the moment there is long delay until the SAP logon screen appears.

Running niping always ends up in a connection abort. Even if i execute this command on the server itself.

Can you reproduce this issue with niping ? Would it be OK or normal that niping ends with a connection abort WSAECONNABORTED ?

Thanks.

Hi Sebastian,

Are you also seeing the WP disconnects in the SM21 and dev_w* logs?

Also what is your OS/DB?

Thanks,

Hello Sebastian,

Can you share the niping output from the failure that occurred when you executed niping at the server itself?

After you are able to logon, can you access the transaction SM50?

Do you see all work processes taken, or are there free dialog processes?

(share a screenshot, if possible).

Regards,

Isaías
