Hey, guys
I've observed messages accumulated inside SYSTEM.BROKER.WS.REPLY rapidly yesterday. We used HTTPInput and HTTPReply.
Logs indicate time spent before going to HTTPReply is tiny, around 100ms each. However HTTP requesters have waited more than 30s to receive the response. So I deduced HTTPReply is working RATHER slow.
I did not have chance to take a httplistener service trace when it occurred. And the phenomenon went away after msgs accumulated inside SYSTEM.BROKER.WS.REPLY begin to expire.(After 3 hours) And the issue is not reoccurring so far.
My question is, for what reason can msgs accumulate inside this SYSTEM.BROKER.WS.REPLY? I tried sending request through NetTool, then pause at a breakpoint inside MBT, then kill NetTool process, ensure netstat -an gives no ESTABLISHED connection to 7080, then continue the flow. However NOTHING is left in SYSTEM.BROKER.WS.REPLY. Is there any way to simulate the phenomenon?
Thanks in advance.

say something, please. anyone interested?
i suppose it has something to do with httplistener's built-in time-out value. anyone knows if there's such a value?

Interested yes. Possessing useful information, apparently not.
You might find you get more responses after the Easter break.

Hi, victor, thanks very much.
I forgot to add the version info. I'm using MB 6.0.0.1, and testing on MB 6.1.0.4
