Just some WAGs:
1. You could turn OFF TSVN Cache -- do all your problems go away? Or,
limit it to the source directories.
2. You could run in a VirtualMachine (VMware, VirtualBox, etc.) and
use the VM specialized debuggers to see what's going on.
3. In stall AntiFreeze (http://www.resplendence.com/antifreeze) - it a
last-ditch process manager that freezes running programs. You may be able
to see which programs/processes are explicitly causing the problem.
Good luck.
