java.net.SocketException: Broken pipe (Write failed) in JMeter - jmeter

Question

When I run a distributed test with JMeter, I get the following error on some slave clients. For this reason, for example, if I send 10000 requests, only 5000 requests go.

I looked in the etc/ssh/ssh_config settings but it doesn't seem to be because of it.

It looks like JMeter slaves cannot report results back to master due to networking issues. If you're using SSH tunnels for establishing the connectivity you might want to check SSH server logs for any suspicious entries.
From JMeter perspective you can check the following:
RMI ports which are used for bi-directional communication should be open and accessible
You can also play with batching properties like num_sample_threshold and asynch.batch.queue.size and try to setting it to lower value so sending results would occur more often and the size of the chunk would be less.
