This should never happen. Can you reproduce the issue and give us further details on the queries involved?

I guess the problem has been fixed in the 7.8 snapshot. Could you please give it a try and report back?

optimize Improper use? Potential bug? Your feedback is welcome:
Does the error occur when opening the database, or when you try to optimize it? In the latter case, you could tr the "optimize all" command. In the first case, it seems your data itself has got corrupt. In this case, you’ll need to create a new database, or restore an existing backup.
Please read our article on transactions to get to know more about locking problems:

Hi,
are you using RESTXQ-`forward`s or `redirect`s, and redirecting to this function call? We have been investigating your issue a little bit, but have not been able to reproduce it yet. Did you ever have problems with that database? It might have been broken before this issue. Can you verify the database using the `INSPECT` command?
It would be very helpful if you could test it using the most current BaseX 7.8 Beta release, and if you’re able to reproduce it (you’re writing it sometimes happens; can you have an estimation on how often it happens: ratio error calls vs successful calls)?
Regards, Jens
Thanks. I have created a new database , can't reproduce it. BYW, is there a way to scheduler backup task?

You could use cron jobs for that, calling `basexclient` with the backup command.
