I was getting rather horrible system crashes (half of UI restarting and freezing every few secs) reliably after installing BlockBlock and it stopped when I disabled them.

Console:

No source file, test, or entry point is identified in the report. Start by reproducing the crash with BlockBlock enabled and compare the Console and system.log output with BlockBlock disabled; done means identifying a BlockBlock-related cause for the kernel memory growth and verifying that the system no longer reaches zone-map exhaustion.
