Subject [jira] [Commented] (QPID-2410) perftest hang in SSL on Windows with large buffers
Date Mon, 04 Apr 2016 12:57:25 GMT

    [ https://issues.apache.org/jira/browse/QPID-2410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15224067#comment-15224067

Tobias Nöll commented on QPID-2410:

Hi Rob, thanks for this information. I tried to change this in the javabroker (ServerDelegate.java).
However, appearantly the new value (16*1024-1) is not respected. This is what the protocol
trace of the client outputs:
2016-04-01 13:51:35 [Network] trace RECV [[]]: Frame[BEbe;
channel=0; {ConnectionTuneBody: channel-max=256; max-frame-size=65535; heartbeat-min=0; heartbeat-max=30;
2016-04-01 13:51:35 [Network] trace SENT [[]]: Frame[BEbe;
channel=0; {ConnectionTuneOkBody: channel-max=256; max-frame-size=16384; heartbeat=30; }]

So appearantly the client sends with max-frame-size=16384 (as expected) but the broker still
sends with max-frame-size=65535 (despite the changes in ServerDelegate.java). Or am I interpreting
the values wrong here?

>             Project: Qpid
>          Issue Type: Bug
>          Components: C++ Client
>    Affects Versions: 0.7
>         Environment: Windows client, Linux broker
>            Reporter: Cliff Jansen

>         Attachments: ssl_windows_patch.patch
> The following command:
>   perftest --count 1 --size 102400 -P ssl --port 5671 --broker linuxhost --username testuser
--password secret --mechanism PLAIN
> hangs on a Windows client.  Reducing the message body size to 1024 bytes makes the hang
go away, as does turning off SSL.
