[basex-talk] Optimize Exception

Hi all, unfortunately during a nightly backup + optimize procedure the VM on which we run an "older" 7.7.2 basex server went out of disk space. This morning I've been able to recover partially. I've been able to take a backup and to recreate the indexes with the "create index *" command. Now the system is operating again and clients are inserting data. The automated procedure is based however on the use of the optimize command which is the only thing that has not restarted to work yielding ArrayIndexOutOfBound Exception. Will it be necessary (sufficient?) to reinstall a fresh version and reimport the backup or is there another way out? Thanks a lot for any hints. M.
