Bummer. Did I miss the bright red warning about that in the
documentation, or is it not there? What other significant tasks are
performed synchronously?

I changed the shell script to just append check results to a file, and
then sent the content of that file using send_nsca once every 15 seconds
- totally separate from the Nagios process.

No noticeable improvement though, I'm afraid. Still the inverted shark
fin shape in the graph :(

I switched back to Nagios scheduler at 14:00.
