I don't use the directive "FORCE HTTP 1.0", I therefore infer that I am HTTP 1.1.

How to verify that I'm not running out of sockets in my TCP/IP stack please ?

>             Project: Synapse
>          Issue Type: Bug
>          Components: Transports
>    Affects Versions: 1.1.1
>         Environment: Windows XP SP2, JDK SUN 1.5.0_15
> Ubuntu Server 6.10, JDK SUN 1.5.0_15
>            Reporter: Nicolas KOHUT
>            Priority: Critical
>
> Synapse has some networks problems.
> When it is stressed, is freeze synapse in transport http.
> This behavior is obtained by influencing 2 parameters:
> - the number of competitors access (number of thread).
> - the size of messages sent.
>  
> More generally, the higher the speed is high (combination of 2 parameters above) synapse freezes more quickly.
> A simple test case (using JMeter):
> - Install distribution synapse-1.1.1 default.
> - Setting up a proxy with sequences in and out empty.
> - Launch a thread (1 single thread is sufficient ...) which calls the proxy with a message 6Ko infinite loop. The thread sits 100 ms between each call.
> Synapse must freeze (random) after about 2 000 calls (5 max 000).
> The freeze takes place at a rate of 7 messages (6Ko) per second ...
>  
> The only configuration synapse that I could find is the file in the folder synapse.properties Conf of synapse.
> This file can affect a pool of thread used by synapse. Increase the various parameters of the pool has no impact and does not correct the problem.
> Listed JVM, jconsole indicates that there is no leakage and no memory thread in deadlock.
> Finally, the synapse approved http requests with nio-http (I do not know more).
> Conclusion:
> The simple test presented above is surprising. Synapse seems not to hold a charge very light.
