Environment: ubuntu 12.04
memery 20G
Reporter: HuangTongwen
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 you
have meets the same or similar problem,please tell me.
I would be grateful if you could help me.
