hi,all. I am new to Solr.
when i query solrcloud4.1 with solrj, the client throws exceptions as
follows.
there are 2 shards in my solrcloud.  
each shard is on a server with 4cpu/3G RAM, and jvm has 2G ram.
when the query requests get more and more, the exception occers.

ps: lbhttpsolrserver seems to allocate task imbalance...some node get a much
heavy load, while others may be not.   i use nginx so that task could be
more controllable.  is this right?


please help me out, Thank you in advance. ^_^
