[jira] [Commented] (IGNITE-1294) Assertion in TCP communication
SPI: client already created
[ https://issues.apache.org/jira/browse/IGNITE-1294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14716668#comment-14716668 ]
Denis Magda commented on IGNITE-1294:
-------------------------------------
The race is possible between the NIO server and any Thread that calls {{TcpCommunicationSpi.sendMessage}} method.
Will investigate further in order to make up a fix.
