But this morning, it didn't start after 10-15 minutes... Then, I went to lunch, and one hour later, it was up and working ! So, you were right, it's just a delay problem... As far as I remember, I installed MySQL and NDOUtils to test the NagVis extension. But it was just a test, and I don't use it. So, maybe I could disable NDO completely. Are there any good reasons for me to use NDO (Other than writing my own software to query MySQL databases directly) ?
