I dont know why, but its happened only on my work PC.. at home its all rigtht.. I'll try to understand what is the reason..I need more detailed info about what you do when you get this message, and the message itself copied exactly how it is. The content of Maya console window will be very helpful to catch the reason of it (with "Verbose mode" enabled in Octane render settings) - you may just post the screenshot if the console has not many messages...
