Subject [jira] [Commented] (HTTPASYNC-109) Requests in AbstractNIOConnPool.pending stays forever.
Date Mon, 01 Aug 2016 17:47:20 GMT

    [ https://issues.apache.org/jira/browse/HTTPASYNC-109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15402487#comment-15402487

Bindul Bhowmik commented on HTTPASYNC-109:
------------------------------------------

 Kirill,

Have you tried using the  setSoKeepAlive option on the IOReactorConfig? Also, since the pending
set is growing, have you checked if your application is consuming all responses (including
error responses)?

Bindul

P.S. I think this is more appropriate as a discussion on the users mailing list.

> 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.
