Cache overflow kills the driver. The only way out is to disable it. Then
see above. You can enable it with the resync suppressed, or allow it to
resync. The default is resync.

You'll also get a resync if the engine determines that the cache file
(*.tao) is corrupt. It will delete and replace it with one where the
first event in the new file is <sync> to cause a resync, again on the
assumption that you actually want everything in sync, and it needs to go
fix anything that it missed.
