When working on really large files (Hundreds of nodes), Nuke may crash when using the 'Clear' or 'Close Comp' functions.
This is a regressive issue, which has appeared in Nuke 11.
Update:
Upon further investigation, this issue appears be caused by linked Knobs. When Knobs are linked, a callback is created on the Knob which provides values, which holds a pointer to the Knob that receives values.
When the receiver is deleted, the callback is removed so that the provider isn't holding a dangling pointer. The provider can sometimes be replaced on the receiver, and in that case the old provider didn't have its callback removed.

Steps to reproduce
1) Open the attached file in Nuke11 (or your affected Nuke script)
Note: The file may take several minutes to load, try not to click on the process or it may go unresponsive
3) Once Nuke has loaded, either clear Nuke via 'File -> Clear' or close the comp with 'File -> Close Comp'
Result: Nuke will freeze and be unresponsive for several minutes, then crash to desktop
Workaround
- For current scripts with this problem, attempt to 'Precomp' sections of the project, this will decrease the file size and memory usage.
- For future scripts, consider precomping sections of your project using the 'LiveGroups' tool.
