Subject: OutOfMemoryError Java heap space after using ReadThrottleFilter
Hi, all
Since I want to control incoming messages retrieved from SMSC, I decided
to use ReadThrottleFilter to block excessive messages.
The code snippet listed as below:
// Executor used to control read throttle
private ScheduledExecutorService throttleExecutor = Executors
.newScheduledThreadPool(1);
connector = new NioSocketConnector();
connector.setConnectTimeout(connectTimeout);
connector.getFilterChain().addLast("codec",
new ProtocolCodecFilter(new
SMPPCodecFactory(false)));
connector.getFilterChain().addLast("exec", new
ExecutorFilter());
connector.getFilterChain().addLast("throttle",
new
ReadThrottleFilter(throttleExecutor));
But under high workload, the system still throw such exception:
Exception in thread "pool-5-thread-3" java.lang.OutOfMemoryError: Java
heap space
Who can tell me how can I achieve flow control aim? Does
readThrottleFilter can't limit message flow?
