> Each error contains same message except of heartbeatTs field.
> This error repeats approximately every second. Not all of Ignite instances are affected. We have figured out that problem is caused by Nessus security scanner. It walks over all boxes and runs some security checks. It looks like one of security checks (which can be http request) causes Ignite to fall into infinite loop of errors. We think that nessus opens a connection to Ignite, then connection is closed by nessus, but Iginite won't kill the socket.

> We have already updated Ignite to latest version.
