Subject Lucene index causing Too Many Open Files
Date Thu, 17 Jun 2004 14:31:02 GMT
     We've got a lucene search index that we use to search (and
delete) a couple thousand items. It runs fine for a few days, and then
it complains about "Too Many Open Files". I am running on Red Hat 7.3.
The user that the webserver runs as, has an unlimited number of files
it can open. That's what makes this error so strange. We're optimizing
the index every hour, also.
     I saw in the old lists that several people have had this problem,
but there was no solid answers as to how to fix it. Any ideas out
there? TIA.

The error in the logs is:

java.io.FileNotFoundException: /home/foobar/index/_dh2.f5 (Too many open files)
