I’m noticing that ferret-write.lck sometimes stays in my index
directory and throws exceptions whenever someone tries to do a search.
Apparently there are some cases where ferret doesn’t realize that the
file is old and can be deleted. I’m wondering what the best way to
recover from this error is. Am I safe just writing a cron job that
deletes this file if it is over 10 minutes old or something? Is there
any additional cleanup that I need to do?
