I have a dev system running 5.5.0. I am seeing a lot of
NoSuchFileException errors (for segments_XXXfilenames).
Here's a log excerpt:

I did not include the full stacktrace, only up to the first Lucene/Solr
class.
Most of the error logs are preceded by a request to the /admin/luke
handler, like you see above, but there are also entries where a failed
request is not logged right before the error. My index maintenance
program calls /admin/luke to programmatically determine the uniqueKey
for the index.
These errors do not seem to actually interfere with Solr operation, but
they do concern me.
Thanks,
Shawn
