You shouldn't get any filesystem errors when searching and indexing 
simultaneously. The only error you might get under normal operation is lock 
timeouts. In this case, you should consider fast updates.

But the errors you're seeing indicate a different problem that probably won't 
be cured by fast updates.

This is caused by a known bug. Unfortunately, the fix wasn't committed when it 
came up for the first time:

I'll make sure that the fix gets into the next release.

If you're (re)indexing thousands of documents and don't want searchers to be 
locked out, you should consider indexing batches of documents and sleep 
between each batch to allow concurrent searches. I'd start with several 
hundred documents per batch and and sleep for maybe 2 seconds. This thread 
contains more details:
