Connection lost to user XY

[Former Member]

Hello! We use mobile Windows XP Embedded machines with SAP GUI 6.40 on fork lifters. The connection is provided via WLAN. But it happens from time to time that the SAP GUI hangs and they have to wait (for 3-5 minutes) until the "connection lost" error comes or they reboot the machine. What is happening here? The log has 2 entries for each break down (translated from german):

a) system call recv failed (errno 10054)

b) connection to user 6159 (NUMBER), Terminal 59 (NUMBER) lost

I checked the network with a mobile notebook and it looks ok. I don´t think it´s the wireless network. It must be something else. It can happen while performing a transaction, also when logging in.

Thanks for any help!

It´s patch level 28. I will see if I can try to use 7.00... strange thing is, if there are multiple SAP windows open, only one hangs, the others run ok.
