Fuseki starts producing 500 errors if rapidly sent a sequence of queries
------------------------------------------------------------------------
Key: JENA-181
URL: https://issues.apache.org/jira/browse/JENA-181
Project: Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Fuseki 0.2.1
Environment: Mac OS X Lion
Reporter: Rob Vesse
It is fairly trivial to cause Fuseki to start generating a 500 : Direct buffer
memory error code in response to queries simply by sending a sequence of
queries to it with no delays between them, even with a short delay e.g. 0.5
seconds Fuseki will typically get into this state at a similar point.
Attached is a simple test case which fires SELECT * WHERE { } queries at a
local Fuseki instance, for me this reliably fails on the 25th iteration,
turning on --debug and --verbose for Fuseki and modifying the log4j.properties
file to set DEBUG level for everything didn't show anything particularly useful
on the command line so I have no idea what the cause of this may be beyond
something related to java.nio.HeapByteBuffer
