I am running 6 scripts, each running on its own schedule. I noticed many times they are not running on schedule. When I manually run one of these for a test, I get this error:
system is busy (12)
My scripts are monitoring latency and packet loss then recording by logging error if they cross certain thresholds. The first 3 scripts are running flood-ping of 1 packet to different IP addresses every 10 seconds (I call these "probe" scripts). The other 3 analyze the statistics gathered by the first 3 every 4 minutes (I call these "analyze" scripts).
