I have an older Linux operating system hosting my license manager daemon. Upon startup, I receive several of the following error message: MLM: error while loading shared libraries: /mathworks/etc/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: ELF file OS ABI invalid
The MLM process eventually exists with a non-zero status: 88 14:48:29 (lmgrd) MLM exited with status 127 () 89 14:48:29 (lmgrd) Please correct problem and restart daemons
I am not able to update the OS on this system.
Is there a way I can move forward without changing the license server's OS?

Oddly, I received the same error (MLM exited with status 127 ()) mentioned above, but not the more useful "MLM: error ... file too short" message described and resolved in this question. The solution was the same (luckily, I had already solved this problem last week, but rebuilt my system and forgot to re-do it, so the original post mentioning libstdc++.so.6 sparked my memory).
For anyone else having this problem, go to the answer of the question I linked in the previous paragraph for full details. Or, find your license manager install folder, and create the symbolic link.
>> ln -sf libstdc++.so.6.0.17 libstdc++.so.6
The numbers are likely not constant, so double check those. And the line above is meant to be run from the <flexlm>/sys/os/glnxa64/ directory.
