Queue Overrun

[Duchassin Frederic]

Yes I already read what you said.
The problem is that even if I set a big queue size (100 MB) I get OVERRRUN.
So I read the "current-level-bytes" parameter and this parameter is lower than max-size-bytes.
(I don't want to disable queue depth by setting max-size-bytes and max-size-time to 0 )
Do you really believe that it is a normal behavior ?

You seem to have missed my first reply:

    Likely because you didn't disable the "max-size-time" and/or "max-size-
    buffers" property. It is set to 10s and 200 buffers respectively by
    default. Set these to 0 to disable.

Queue2 default configuration is different, as it targets a different use case.

Nicolas
