I am having the same problem with YaST2 on all 10+ of my SLES 11 SP1 servers that run IBM HTTP Server (IHS). The issue is that just about everything I try to do using YaST2 results in the screen flashing and nothing happening. Upon exiting YaST2, there is a message in PuTTY for each task attempted which is:

/sbin/yast: line 443: 37014 Segmentation fault $ybindir/y2base $module "$@" "$SELECTED_GUI" $Y2_GEOMETRY $Y2UI_ARGS

Just about everything attempted in YaST2 results in the above message.

I received the above message when I went to Hardware --> DASD. When I tabbed to DASD and pressed Enter, the screen simply flashed as stayed on the YaST2 Control Center screen.

These servers are a mix of test and production servers. None have been modified since September, 2011, when they were upgraded from SLES 11 SP0 to SP1. YaST2 worked fine after the upgrade to SP1 and stopped working sometime in February.

A few differences between these servers and the ones that run WebSphere Application Server (WAS) are:
- The servers running IHS run with 128 MB of memory and the servers running WAS are at 1GB and above.
- The servers running IHS are in a DMZ and the servers running WAS are not (I don't believe that this has anything to do with the issue). Thus, the IHS servers can't connect to Novell for updates without me re-IPing then to a different network for the upgrade process.

Does anyone have an idea as to what I need to do to resolve the segmentation faults?
