Hi again,
i have verified, that the durable subscriber on reconnect is configured
correctly,
when I set keepDurableSubsActive to false on the broker.
Best regards

Thanks Gary,
to me it looks like configure is not being called when the subscriber
reconnects.
I ll try to trace that later.
I'll create a JIRA for now.
Thanks
Andreas

that looks like a bug and you should raise a jira.
however the broker config will only override the default value, so a
client
provided value will take precedence if it is specified.
It seems the client does not specify a value, the broker 5 is used the
first time, and the default on subsequent reconnects, so that is not
ideal.
it looks like there is call to configure the durable sub at -
https://github.com/apache/activemq/blob/d54e0d6ab590b6a6148a5e2629c45b95d3f40eb8/activemq-broker/src/main/java/org/apache/activemq/broker/region/TopicRegion.java#L317
maybe keepDurableSubsActive is relevant.

Hello,
I am using Active MQ 5.10 within a Karaf based application and have
spent
the last couple of days
investigating an OOM Exception we were getting occasionally.
It turned out, that the OOM happens occasionallly when we reconnect a
durable subscriber that
would have a large amount of data in it even though we have specified a
rather small prefetch
size for durable subscribers (5) within the broker configuration.
Further analysis showed that after closing and reconnecting the same
subscriber it has a prefetch
size of 1000 (the default value). That would cause an OOM if those 1000
messages exceed the
JVM heap size.
Specifying the prefetch size within the broker url from the client side
works fine, but we would like
to keep the setiing on the broker side as not all clients are our
development responsibility.
I have attached a test case that demonstrates this observation.
Is this a know issue or should I create a JIRA ticket for this ?
Thanks and best regards
Andreas
