<DIV>Hi 张明涛,</DIV>
<DIV></DIV>
<DIV>Regardless of whether messages are published as persistent, all messages</DIV>
<DIV>are held in RAM. If you publish messages without consuming them them you</DIV>
<DIV>will eventually run out of RAM. Your server seems to have enough memory</DIV>
<DIV>for 9000 messages.</DIV>
<DIV></DIV>
<DIV>You will not be able to open any new channels to the broker after the</DIV>
<DIV>memory limit has been reached, but existing consumers may continue to</DIV>
<DIV>consume messages.</DIV>
<DIV></DIV>
<DIV>The source repository currently contains a new persister in branch</DIV>
<DIV>(bug21673) which will solve your problem. This feature is currently</DIV>
<DIV>undergoing QA.</DIV>
<DIV></DIV>
<DIV>The memory high-watermark is somewhat relevant to your situation. This</DIV>
<DIV>can be set in the config file (see</DIV>
<DIV>http://www.rabbitmq.com/install.html). The default of 40% is recommended.</DIV>
<DIV></DIV>
<DIV>Regards</DIV>
<DIV></DIV>
<DIV>Emile</DIV>
<DIV></DIV>
