Expected behavior

If gravity update fails due to disk space limitations a fallback to the old database should happen. PiHole should remain productive.

Actual behavior / bug

Once gravity update fails due to limited disk space for DB generation, FTL process raises to a CPU load of 100% and the system does not resolve DNS requests anymore.

Steps to reproduce

Steps to reproduce the behavior:

1. Limit diskspace for database generation (e.g. using fallocate)
2. Run gravity update
3. PiHole is now not resolving DNS queries anymore, FTL process is at 100% CPU

Debug Token

No debug token available since upload fails due to inoperable PiHole. Debug logfile available.
