<DIV>Hi guys,</DIV>
<DIV> </DIV>
<DIV>I am quite new to RabbitMq and now try to learn it from the tutorial. I
installed the windows version and the LINUX version (CentOS 5.5) of RabbitMQ
2.8.2. The Erlang version is R14B03 in Linux. In Windows, everything is fine.
But in CENTOS5.5, after sending the message, the program cannot exit and always
stuck. Hence, the receiver also cannot get the message. Can you point
out how to debug it? Thanks a lot!</DIV>
