HuangTongwen reopened SOLR-6138:
--------------------------------
I am sorry for the first time I decribe that problem is not complete.
At this experiment,we have adjusted the max files numbers that linux can
open.we set it 165556 it is very big than the default number.At the same time,
we also have changed the znode size limit.We need know that why exception
happened like that. Sometime I suspect that it is a problem in solr.

> We want to enrich our search ability by solr.We do an exercise for test that
> how many cores in one machine solr cores can support.
> We find we can create more than 2000 cores without datas in one machine.But
> when we create cores with data ,we just can create about 1000 cores,after
> more t han 1000 cores,we meet many errors like following I will apend it .If
