missed heartbeats in TIBCO
ActiveSpaces. Symptoms: ActiveSpaces as-agents stops responding with messages like:
1). consecutively missed 3 heartbeats from server
2). hosts_impacted (1) <= cluster_suspend_threshold (-1).. waiting for 30000 msec
Cause: Some of the causes are:
1. Network latency, the communication between nodes has network issues and they can't respond timely.
2. Machine is too busy with high CPU usage and high memory usage, causing heartbeats that can't respond timely.
