I ran my ELK setup on a large set of data with elasticsearch default  
settings but with Xms = 2G on a red hat server with 32 GB RAM, 600GB HD and  
after reading around 64 lac log lines my logstash console gives the error:

Exception in thread "elasticsearch[logstash-XX-23664-4104][generic][T#6]"

I am doing the load testing forst time on ELK set up. So doe sthe above  
error mean ES with default settings can take only this much load?  
Shall I need a another node ??
