So that usually means 1 of a couple of things
1) You didn't have space for us to save the free space cache
2) When trying to write out the cache we hit one of those cases where we would
deadlock so we couldn't write the cache out
It's nothing to worry about, it's doing what it is supposed to. However I'd
like to know why we're not able to write out the cache. Are you running close
to full? Thanks,
Josef
