Hi Oleg,
I am using
java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
Java HotSpot(TM) Client VM (build 1.5.0_14-b03, mixed mode)
I find this suspicious as TimeoutController is used only when running on
pre 1.4 JREs.
(1) double-check the server side environment and make sure the correct
JRE gets picked up.
(2) replace DefaultProtocolSocketFactory with a custom impl that uses
Java 1.4 methods for controlling connect timeouts.
Hope this helps
Oleg
I think I am seeing the threads from the TimeoutController:
/**
* Executes <code>task</code> in a new deamon Thread and waits for the
timeout.
* @param task The task to execute
* @param timeout The timeout in milliseconds. 0 means to wait forever.
* @throws TimeoutException if the timeout passes and the thread does
not return.
*/
public static void execute(Runnable task, long timeout) throws
TimeoutException {
Thread t = new Thread(task, "Timeout guard");
I did not see any switch regarding java 1.4. in the code.

From the code I would guess that I should not end up having more than
HttpConnectionManagerParams params = new HttpConnectionManagerParams();
params.setMaxTotalConnections(...)
Threads called "Timeout Guard" flying around in my JVM. Unfortunately I
limited it to 15 connections in total and find around 25 of those threads
at
times. On my kind of limited virtual server that is currently causing
some
problems.
I would appreciate some help. Thanks in advance...
What JRE are you using on that server? Timeout guard threads are used to
unblock socket connect operations on older (<1.4) JREs.
