> While adding documents to an already existing index using this build, the 
> number of open file descriptors increases dramatically until the open file 
> per-process limit is reached (1024) , at which point there are error messages 
> in the log to that effect. If the server is restarted the index may be corrupt
> commits are handled by autocommit every 60 seconds or 500 documents (usually 
> the time limit is reached first). 
> mergeFactor is 10.
> It looks as though each time a commit takes place, the number of open files  
> (obtained from " lsof -p `cat solr.pid` | egrep ' [0-9]+r ' ") increases by 
> 40, There are several open file descriptors associated with each file in the 
> index.
> Rerunning the same index updates with an older Solr (built from trunk in Feb 
> 2010) doesn't show this problem - the number of open files fluctuates up and 
> down as segments are created and merged, but stays basically constant.
