Question

What could be the cause of the error "Invalid license key (inconsistent authentication code" on Redundant Servers, when

everything works fine using exactly the same binaries (vendor daemon and lmcrypt) on a single server?

Answer

If the environment variable FLEXLM_ANYHOSTNAME is set on these redundant servers then this could cause this error.

If we unset the FLEXLM_ANYHOSTNAME variable then the 3-server redundancy works fine.
