Taras Tielkes updated AMQ-2660:
-------------------------------
Description:
Running 5.3.1 broken on Win64, using Sun 1.6 x64 JVM.
Maximum heap size is set to 1024M.
We're sending and receiving huge messages over ActiveMQ, and cannot get the
system running in a stable way.
For purposes of testing, we're sending text messages of 100M characters, I
guess this means 200MB in-memory, since Strings are stored as UTF16 in JVM
memory.
However, with the broker having a 1GB heap this should work - we assume.
Testing with a single producer, single consumer.
We're using a slightly modified activemq.xml:
1) "systemUsage" block enabled, and configured as shown below:
-------
<systemUsage>
<systemUsage>
<memoryUsage>
<memoryUsage limit="500 mb"/>
</memoryUsage>
<storeUsage>
<storeUsage limit="1 gb" name="foo"/>
</storeUsage>
<tempUsage>
<tempUsage limit="100 mb"/>
</tempUsage>
</systemUsage>
</systemUsage>
-------
2) producerFlowControl disabled, as shown below:
-------
<policyEntry queue=">" producerFlowControl="false" memoryLimit="1mb">
-------
Description of symptoms:
1) Starting up producer, let it run until store gets full. This typically works
out to 9 or 10 messages, each being 100M characters in size. From this I'm
inferring that ActiveMQ stores these in UTF-8 format.
2) Starting up consumer
When starting the consumer, ActiveMQ broker fails with OOM shown below:
-------
ERROR | Failed to page in more queue messages
