Subject Re: Too Many Open Files
Date Mon, 28 Jun 2010 21:24:59 GMT
Thanks for responses.
I instantiate one instance of  per request (per delete query, in my case).
I have a lot of concurrency process. Reusing the same instance (to send,
delete and remove data) in solr, i will have a trouble?
My concern is if i do this, solr will commit documents with data from other
transaction.

Thanks
