User right when the houdini license system fails? Jan. 7, 2024, 6:36 a.m.

If things work fine and then suddenly start to cause problems or stop working, most of the time some environmental issues had changed. Did some things change like hardware, additional software, updates. Keep in mind the automatic OS updates. A workstation is often a changing environment due to updates alone.
As of this complicated nature I guess You are lucky to find the problem, but holding someone responsible for this is another thing.
This might be the case for systems that advertise this kind of feature, but this often works only in a very closed system with minimal system changes and very slow development.

If that kind of stability is important to You, I recommend to work on a very limited system with close to zero changes, beside of security critical updates, not automated. Redundancy would also help.
