             Summary: Requests in AbstractNIOConnPool.pending stays forever.
                 Key: HTTPASYNC-109
                 URL: https://issues.apache.org/jira/browse/HTTPASYNC-109
             Project: HttpComponents HttpAsyncClient
          Issue Type: Bug
    Affects Versions: 4.1.2
            Reporter: Kirill Barkunov


Hi!

I have a client built this way:

{code}
IOReactorConfig ioReactorConfig = IOReactorConfig.custom()
            .setIoThreadCount(Runtime.getRuntime().availableProcessors())
            .setConnectTimeout(30000)
            .setSoTimeout(30000)
            .build();
    private CloseableHttpAsyncClient httpAsyncClient = HttpAsyncClients.custom().setMaxConnTotal(150).setMaxConnPerRoute(130).setDefaultIOReactorConfig(ioReactorConfig).build();
{code}

I've noticied that on environment with a firewall enabled (I think it cuts all the socket connection 5 minutes after their establishing) after some time client stops sending https request. After a small investigation I've started to monitor insides of the client and noticied that a few minutes after the client start - AbstractNIOConnPool.pending collection starts to grow. At start it's 0. After few minutes it's 1-2. Then it starts to grow faster and few minutes later it reaches maximum number of connections per route. And it stops work forever. Only AbstractNIOConnPool.leasingRequests grows and no one of the new requests are processed.

Target for all the requests is www.googleapis.com
As I can understand from client insides load is like 1-5 request at a time.
I mean before first "dead" request in AbstractNIOConnPool.pending the number of "leased" and "available" is not more than 5.

Best regards, Kirill.
