MAX CONNECTIONS

[Joan Balagueró]

Hello,

 

I’m testing HttpClient4, and I’ve found the following problem.

 

I set MaxTotalConnections to Integer.MAX_VALUE:

ConnManagerParams.setMaxTotalConnections(this.objHttpParams,
Integer.MAX_VALUE);

 

But when I send 5 simultaneous requests, I get 2 “maxConnections” errors.
The exception is:

 

org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for
connection

If I print the “maxConnections” value inside the exception
(System.out.println(ConnManagerParams.getMaxTotalConnections(this.objHttpPar
ams))), I get: 2147483647. That’s OK.

 

I suppose I’m forgetting something. Maybe
“ConnManagerParams.setMaxConnectionsPerRoute()”. Any help?

 

Thanks,

 

Joan.
