[EP-tech] error on indexer
Hi Ernesto and John,
Xapian index is a flat file (well a set of flat files) so it cannot be
updated by two things at once.? There is a good chance if the EPrints
indexer was trying to index at the same time as you ran "epadmin
reindex".? There will then be two separate processes trying to modify
the Xapian index at the same time, so it will stop one of those process
from gaining access.? Therefore, if you are doing a mass reindex of all
your eprint records, I would advise stopping and then making sure the
EPrints indexer is no longer running.? If you still see the same error
message when the indexer is not running then you can probably delete the
lock file for the Xapian index.? However, there is always an inherent
risk to doing this if somehow some other process is modifying the index
(e.g. another reindex command running elsewhere).? On RHEL-based linux
this lock file will be called flintlock in the xapian directory (e.g.
/opt/eprints3/archives/melt/var/xapian/flintlock).? If you are running
Debian-based Linux (e.g. Ubuntu)? I have a recollection that the lock
file name is different.
Regards
David Newman
