This problem is different then the normal situation where you can increase it with "ulimit -n XXX".
This is a real bug introduced by SOLR-104. As Yonik pointed out, the filter does not close its request and when the searcher is opened for an update (unnecessary) it hangs on to closed files indefinitely. I think the patch on SOLR-173 is good to go - if anyone has a chance to look at it, that would be great. thanks ryan On 2/26/07, Cook, Jeryl <[EMAIL PROTECTED]> wrote:
I remember when using Lucene directly in a project, I noticed this error only comes up if the system is deployed on UNIX boxes..in our case SOLARIS. You can increase the number of allowed "open files" on unix ..i forget the command but the default is 256. We increased it, and the problem went away.(but the patch looks to address it programmatically as well.)
