Lucene errors (unknown format version, and unable to create new writer

[Jason Cantrell, modificado hace 15 años.]

I'm using Liferay 4.4 with Tomcat 5.5.

I'm getting some unusual errors. I've gotten the "Unable to create a new writer" error before, and I've solved it by deleting the .lock file in the liferay/lucene/0 directory. But now I'm getting this "Unknown format version: -4" error, and I'm not finding the .lock file in the usual directory. Can anybody offer any assistance?

I'm getting the following errors in my tomcat window:

Try to delete(rename) lucene/* directories and start portal again.
It looks like index files got corrupted. Liferay should re-create those directories.

It's also a known bug in Liferay which is fixed in 5.1 (if I'm right)

Thanks for the replies. Deleting the lucene directories worked.

It worked for me too! Thanks.
