Subject Broker hangs and cant restart it
Date Fri, 23 Apr 2010 03:25:37 GMT

This is the scenario:

I open three web admin consoles and send 10.000 messages from each console
at the same time. Each message is about 50k. I mark persistence. And all
messages go to the same queue. When the Queue receives 20.000 messages, the
broker appears to hang.
I can see that tmp_storage is consuming all the allocated space so the “Temp
percent used” reaches 100%.

My first question is, why tmp_storage is growing if all messages were marked
as persistent? 

After the broker hangs, I try to shut it down, but the only way is to force
kill it.

Second question: even if the tmp_storage is full, why the broker is not
shutting down in a normal way?

After killing it, I restart it but it hangs and does not complete the

But, if I configure the “tempUsage” a Little bit higher, then the broker
starts again and the problem gets solved.

So, my last question is, why I need to increase tempUsage in order to
restart the broker?
