Nagios Error General Time-out (Alarm Signal)

Nagios monitors the network issues caused by overloaded data cables or connections. It also checks for issues due to routers, switches, and other network parts. It can easily monitor the availability, uptime, and response time of every node on the network. And provide the findings in a number of visual representations.

When it forces recheck on ‘orphaned processes’ from a restart of the service, we may encounter the error. In this article, we will look into some of the solutions for the error.
