Service 'indexer' exited with status 2

Hello,
I have a problem with the indexer.
It does restart caused by problem with always the same index IDX_DocumentStatusLog_deleted_UpdateTime

I did try to remove and rercreate the index without success.

Server Version is: Community Edition 7.0.2 build 6703

Service 'indexer' exited with status 2. Restarting. Messages:

Any ideas?

The index data file seems to be corrupted. You can try to run forestdb_dump on the file and see if that works. Removing the index, removing the files (data.fdb.*) files and recreating the file should recreate the index. If you run into issues. please share the index log files. You can run cbcollect_info and get a zip file of the logs.
