I thought I’d be smart and upgrade our server to the 64-bit version of RHEL5. Well, after upgrading I had many problems. A big one was this error:
[root@edg ~]# su - maryh /bin/hostname: error while loading shared libraries: libc.so.6: wrong ELF class: ELFCLASS32
If I can’t run a simple hostname command, then there are probably lots of other issues. Thus, I’m reinstalling again with the 32-bit version.
