> Priority: Critical

> After several hours of script tests (create and drop users, keyspaces and
> tables) exception is thrown:

> {code}
> I added some logs to *deleteWithConfirm* and it showed that this file really
> was deleted by previous delete action, i.e. it was second attempt to delete
> the same log. Commit log with next number exists in the same time, so log was
> switched.
> I disabled assert and it seems to have no no bad effect.
