Hongwu LU updated AMQ-2019:
---------------------------
Description:
i have a program which use stomp to receive messages from activemq,
when i start it and wait for several minutes before close it, everything is ok.
but if i wait for one hour, for example, when i close it, then i find from the
management page, the two consumers are still there.
and if i restart the program with these tow hanging consumers, then i could not
receive any message.
i do not know whether it is a bug or just my program problem, sorry for disturb
you here for an analyse, please.
here is my program:
#!/usr/bin/perl -w
