Older HealthCheck versions contain a defect that can trigger Internet Control Message Protocol (ICMP) pings to SyncIQ targets that never stop. When this occurs, a new ping process is started for each time the check runs for every SyncIQ policy, and these processes continue indefinitely.

In prolonged scenarios, this may lead to increased network utilization, congestion, and potential packet loss.
