why this error comes sometimes again and again 1 or 2 days how to solve this 
permanantly what is exact problem for this.
-------------------------------------------------------------------------------------------------------------------------------------------------

And also i found this for web some others really this is the cause?

The Exact Problem: "The Silent Kill"
The error Timeout waiting for idle object happens because of a 3-way conflict:

CloudStack Pool: Keeps connections open in a "pool" to save time. It expects 
these to stay alive for hours.

HAProxy (The Culprit): By default, HAProxy often has a timeout client and 
timeout server of 50 seconds. If a connection is idle for 51 seconds, HAProxy 
kills the "pipe" but doesn't tell CloudStack.

The Error: When CloudStack finally tries to use that connection, it finds a 
"dead pipe." It then tries to get a new connection from the pool, but because 
so many connections are now in this "broken" state, the pool becomes exhausted, 
leading to the java.util.NoSuchElementException: Timeout waiting for idle 
object.

Please check and give me exact solution
