i have bunch of java processes that are talking to my ES server. and after  
a while, they start barfing with this exception..

i have seen bunch of mails on this and tried all remedies like setting high  
ping timeout, etc. but nothing seems to work.  
is it related to too much pressure on ES server?

i used to initialize the transport client during startup and use that for  
all subsequent operations. but with this error, i started connecting only  
when hitting ES and then i would close it. and then reopen for the next  
use. but we have a heavy operation on ES and doing this recreation is also  
not solving the problem.  
both client and server are on EC2. i also noticed another side effect of  
constant transport creation - i have monit process which ping the ES server  
health every minute or so.. and it is getting connection failed attempts  
every now and then. this never used to happen before.

any insights? any config on the server side that might help?

thanks
