Hi folks,
I've just spent half the day trying to figure out why messages submitted from a JBossMQ client on one particular machine would silently get dropped from the topic, whereas messages submitted from any other machine would be noticed immediately.
Finally I noticed that the non-working client machine's clock was two hours slow. As soon as I set it ahead to be relatively close to the server's clock, everything started working.
It looks like JBossMQ is using some sort of timestamp from the client to silently drop or ignore messages, which IMHO it should not do.
