Hi All,
I'm using the library Axis 2 version 1.7.3 with HttpClient 4.4.1, and
after 200 request the library throw a TimeoutException from connection pool.
>From stacktrace I found the exeption is throw by the class
PoolingClientConnectionManager,
as reported below

Search into code of library i found the configuration of connection pool:
connManager = new PoolingClientConnectionManager(schemeRegistry);
((PoolingClientConnectionManager)connManager).setMaxTotal(200);
((PoolingClientConnectionManager)connManager).setDefaultMaxPerRoute(200);
configContext.setProperty(HTTPConstants.MULTITHREAD_HTTP_CONNECTION_MANAGER,
connManager);
The connection pool it's configured to have 200 connection for route, I
have made some test and my application fail after until 200 web service
request.
>From log i see this line, to confim my idea:
2016-09-19 16:01:06| DEBUG | Connection leased: [id: 199][route:
{s}-http://XXXX:443][total kept alive: 0; route allocated: 200 of 200;
total allocated: 200 of 200]
2016-09-19 16:01:09| DEBUG | Connection request: [route:
{s}->http://XXXX:443][total kept alive: 0; route allocated: 200 of
200; total allocated: 200 of 200]
I think the connection pool use all available connections without release
it, after that throwing the exception.
I tried to write on Axis2 mail list without luck.
Any suggestions/test to solve the my problem ?
