Describe the bug

Lately I have a crash about every few minutes to 3 or 4 hours if I'm away, and either it reports a ticking LaserIO node, F3 shows 99% Memory Usage, or I get the attached Crashes. I HAVE recently started messing with computercraft, but I have never left any code running. One modification to pack is increased chunk loads from 25-75 through FTB Chunks.

Steps to reproduce

Start Single Player world.
Open to LAN (to let farms, reactors etc Run)
Lock Computer (Win+L)
Walk Away
Come back a few hours later
Crashed or just 1 frame per 5-10 minutes.

Expected behaviour

.. Walk Away, Come back, Server still running, memory usage under 70%.

Screenshots

No response

Additional information

Would do screenshots of the F3, but it's lagging so bad my computer would probably catch on fire by the time it finished expanding from the sides of the screen.

Yeah. If I sit and watch the F3 screen, Allocated slowly crawls upwards until the limit and the memory usage does the same. I've tried as low as 6GB, and so far as much as 12. Same result.
