I'm using Debian Jessie with the latest updates. I made a systemd service to run a script when my server starts. Here's its configuration:
[Unit] Description=(my description) [Service] ExecStart=/usr/bin/bot Restart=restart-always [Install] WantedBy=multi-user.target
/usr/bin/bot is a script running a Mono executable. It consists of:
#!/bin/bash (cd /path/to/my/executable && mono bot.exe)
(I replaced the path here, but the one on my script is correct.)
When I run the script
/usr/bin/bot normally (simply
/usr/bin/bot on my terminal), it is working as expected.
top reports it's using between 0 and, say, 20% of my CPU, which is normal. But when I start it with
service bot start,
top says it's always using at least 100% of my CPU.
In both cases
bot is working as expected.
What could explain such a big difference in CPU usage?
