Hello Lubos, I'm not so happy with this decision, because I think, that this is not an IBM-problem but a problem of the libraries in /lib or rather /usr/lib, perhaps the glibc. The other libraries, needed by the Notes Client didn't change significantly since Suse 42.3. Suse 43.2 did use version 2.22 of the glibc, Leap 15.x uses 2.26 and Tumbleweed is up to 2.30. With Suse 42.3 the Notes Client was ok. When I use the Tumbleweed libraries on a Leap 15.2 system when starting the Notes Client, he starts. After the start has finished, I can return to the Leap libraries. The Notes Client continues working. :) The changing of the libraries happens simply by renaming the folders. So I believe, that there might be something wrong within the 2.26-version of the glibc. But I have no idea, how to verify that. That is why I would like to know, what I can do know now? Because the tricky work-around will perhaps not work very long. Is there a possibilty to install a higher glibc-32Bit on Leap 15.2? Guenter
