In order to get our lmgrd command running in 64-bit rhel6, need to install redhat-lsb.i686 package. This installs a bunch of other packages as well.
Before installing this package, the lmgrd command gave this error:
[root@server bin]# ./lmgrd -bash: ./lmgrd: /lib/ld-lsb.so.3: bad ELF interpreter: No such file or directory
Afterwards, it worked fine.
