Hi all,
Recently I noticed that the activemq would stop sending message to the
consumers after some time. Here is a unscientific test to duplicate this
issue:
The test involved creating around 7 durable subscriptions and ctrl+c'ing
them. Once the durable subscriptions were registered, around 8 publisher
processes were started, each process wrote a 'fortune cookie' , in an
infiniteloop, to the activemq server. In parallel, 3 subscriber
processes were started. The 3 subscribers were randomly stopped and
started, cyclically. At about 15000 messages (on each of the 8 write
processes), activemq stopped sending the message to to the subscribers
and the publisher processes hung on "syswrite" to activemq. Then
another publisher process was started, activemq actually accepted
messages, but none of the subscribers received it.
The next test involved, using mysql as the data store (instead of the
default journalled db). The same steps were followed and at about 18000
messages (on each of the 8 processes), activemq stopped sending messages
to the subscribers.
Im using activemq 4.0.2. Any suggestions/help is appreciated. Thanks
