Today we’ll take a look at the causes for this error and see the fix.

What causes ‘Nagios did not exit in a timely manner’ error to occur

Before we get into the solution part of this error message, let us see what causes this error message.

Normally, you come across this error message while stopping or restarting the Nagios in larger deployments.

This error mainly happens due to the various factors in larger deployments. However, it is just a timeout issue

Sometimes, if any service check that is hung, or rather not returning output, then it will cause Nagios not to exit properly.

How we fix the error ‘Nagios did not exit in a timely manner’

Now let us see how our Support Engineers resolve this Nagios error message for our customers.

Since this is just a timeout issue, you can simply update the Nagios init script to increase how long the script is allowed to run.

So, edit the file of /etc/init.d/nagios. Then find the below line.

for i in 1 2 3 4 5 6 7 8 9 10 ; do

Now, change the above line to below one:

for i in {1..90} ; do

The above line changes the timeout to 90 seconds. However, you can increase to a larger number as you require.

As a result, this must fix the issue.

Note: The above changes will be overwritten every time an upgrade of Nagios XI or Nagios Core is done. So you would need to re-modify after an upgrade.
