Hey all,
I have faced the following problem, several times across different projects. Sometimes, when manipulating some geometry while IR is running, Interactive hangs (picture stays pixelated) and RAM starts ramping up. I may be sitting at around 30-40% Ram Usage and after a while I am at 99% of 128gb RAM, with Paged file also heavily used. Clicking on STOP at this stage (even before RAM usage hits 99%) does nothing.
Specifically, I was manipulating an Editable Poly, with Chamfer modifier and an instanced UVW Modifier on top. The assigned material also had Displacement, so maybe there lies the culprit.
This one is one of those tricky bugs to solve, as it cannot be easily reproduced. Right now I am sitting at 99% RAM, waiting for 3ds max or the computer to crash, or for IR to magically stop by itself (I remember that on some occasions IR would stop after a while with a RAM Full Error, without crashing the whole program).
I could share the file with you, but I doubt you will be able to reproduce this. One suggestion would be to integrate a failsafe (maybe Corona 8 has this?) where IR would stop when Ram gets full under such circumstances (and not under usual scene load).

Thank you and have a nice day!
EDIT: I submitted a request along with a minidump [Ticket Id #38405]. 3ds max has not crashed, it's just frozen while I generated the minidump. I'm going to murder it now, after half an hour of waiting
