There may have been an IcmpDaemon timeout.

It's seen in the DX NetOps Performance Management Data Collectors karaf.log file found in the (default path) /opt/IMDataCollector/apache-karaf-<version>/data/log directory.

Cause

This error generally revolves around network connectivity problems that could include network saturation or access restriction along the lines of a firewall.

Resolution

This error indicates that the IcmpDaemon (an integral part of the Data Collector) sent out a ping request (icmp). It received a response, but the response did not come back until after the IcmpDaemon gave up waiting for it to arrive.
