Kernel memory leaks
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.

The only other kext I have is VirtualBox but that has been installed for years.
I was seeing it also (even when it was disabled via the preferences). Also strange was the slow down of Time Machine back ups (which might be related to a macOS 10.15.x bug, macOS is set to auto report to ), a workaround might be to grab the installer to uninstall it (not sure if you can export your rules before the uninstall) until a update with a fix comes out.
This may have been fixed (by Apple) in 10.15.6 supplemental
According to: 10.15.6 Supplemental Update "This does appear to fix the kernel zone memory leak which was causing panics when running VMWare and VirtualBox VMs, and seems to have restored stability to memory usage here too."
If you've fulled updated macOS, are you still seeing this issue? thanks!
I'm seeing memory leaks in 10.15.7 as well. While Block-Block (1.0.2) is active, monitoring the output of zprint -d shows a a steady number of allocations hitting zone kalloc.128. After about two weeks up uptime, this zone becomes the largest by far. Disabling Block-Block results in the frequency of allocations to this zone to drop dramatically.
