Hi all,

I have started several Ignite nodes (each running in a separate JVM)
in the same machine. Then I use cache.invoke in these nodes for
updating a cache value. Cache entry is updated successfully.

I have inspected the logs and there are entries like:


16/06/09 23:27:04 WARN TcpCommunicationSpi: Failed to allocate shared
memory segment (switching to TCP, may be slower).

Is it the case Ignite uses shared memory for communicate Ignite nodes
running in the same computer? Any advise on how to avoid the "Failed
to allocate shared memory segment" problem?

Regards

Luis
