License Server Cannot Be Started

If the license server refuses to start on Linux, check the output of

ldd lmx-serv-quantum

If you see something like

./lmx-serv-quantum: /lib64/tls/ version 'GLIBC_2.4' not found (required by ./lmx-serv-quantum) => /lib64/tls/ (0x0000003ca4700000) => /lib64/tls/ (0x0000003ca3f00000) => /lib64/tls/ (0x0000003ca3c00000)
 /lib64/ (0x0000003ca3800000)

it means that this machine can not be used to run the license server, since it requires GLIC 2.4 or newer, and this machine uses GLIBC 2.3 (or lower).
