I had similar problem before, someone changed the stock system libz.so with a newer version libz.so, which yum didn't like it!

One of them was recently completely replaced with identical hardware, so I had to image the old one, and install OS-image on "new" server. But now, when I run yum on the new server, it returns a segmentation fault (even a simple: # yum --help). Googling this, a lot of pages hint for a memory error. But, running a memtest did not show any error. So far, only yum returns the segmentation fault. Does anyone have any clue for this ? Regards, Carel van der Werf
