ChrisB, what version of MLServer? Upgrade to the very latest.
Please try to isolate what plugins may be causing the crash. You can do this be deselecting the plugins (get rid of half) and then restarting MLServer to test. The problem is with combinations (like TT and HAI), that you might get rid of one, but not the other in the half life approach.
I have noticed same error message in MLServer log. That will be fixed, and it might have something to do with any instability issues. this was a new feature where the MLServer now tracks what plugin is launched and then notifies those plugins to shut down when MLServer shuts down. I have also seen MLServer error on shutdown, which is probably related to the launch error.
Regarding licensing, we now are taking orders for the MLHAI plugin:
We will fix the instability and launch error problems. That's a promise. Rest of comments will likely be addressed, but no promises. We too want this to be a very powerful asset, but can't commit until we uncover what the additions will take in resources. X10 / Thermo polling has us scratching our heads, so no commit on that one, but we know it's important. Just hard to commit until we see what's up.
thanx for the great beta test results. As you can see, your voices are heard and are being implemented.
