Which version of OC is this with? There were some leak related fixes very recently.

OpenComputers-MC1.8-1.5.3.53-dev-dev.jar The latest dev version.

OK, will try to reproduce.

@fnuecke it might be same problem as ours.

Hrm, didn't it only happen for Microcontrollers in your case, though?
@lumien231 any OC block in particular that seems to cause it?

I don't have to place any oc blocks for it to happen. The blocks it happens with also aren't components.

@fnuecke It was happening with everything connected to those uC.

Wait, so chunks fail to unload only by OC being present? That's... I have no idea what could cause that. Do the chunks fail to unload or are they immediately reloaded again? In the latter case, mind checking in validate() what keeps it loaded / reloads it?

So i didn't look into it THAT much to be honest, will see whether i can find out what exactly keeps it loaded. I just know that my tes aren't being garbage collected with oc installed.

Hrm, if the chunks actually are getting unloaded, maybe create a heap dump with VisualVM to figure out which GC root keeps them alive?

Okay now i can't reproduce this anymore :P, will reopen this if it happens again.

Allrighty.
inb4 vanilla bug :P
