Wanted to simulate number of connections at a time

[Rambabu]

Hi,

I wanted to simulate number of connections at a time. Tried 5000 connections in separate threads but getting following exception.

java.util.concurrent.TimeoutException
        at com.rabbitmq.utility.BlockingCell.get(BlockingCell.java:77)
        at com.rabbitmq.utility.BlockingCell.uninterruptibleGet(BlockingCell.java:111)
        at com.rabbitmq.utility.BlockingValueOrException.uninterruptibleGetValue(BlockingValueOrException.java:37)
        at com.rabbitmq.client.impl.AMQChannel$BlockingRpcContinuation.getReply(AMQChannel.java:367)
        at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:293)
        at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:621)
        at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:648)
        at standalone.getChannel(standalone.java:34)
        at standalone$ProducerThread.run(standalone.java:244)


Thanks

Hi Rambadu,

please, could you post the rabbitmq log? Make sure you have enough file descriptors. Try “ulimit -n” command on your server.

Kind regards,

Giuseppe

On Linux and OS X, default system limits are not sufficient to have 5000 concurrent connections.
