Systemd-journal is using a lot of CPU. How can I fix this?

Hello,

I find my linode using 100% cpu, and the top results is following:

 %CPU %MEM     TIME+ COMMAND                                                                  
 88.4  2.1   8:45.92 systemd-journal                                                          
 1.7  2.9   0:00.35 apache2                                                                  
 1.7  1.3   0:00.05 apache2                                                                  
 1.3  3.4   0:02.24 apache2                                                                  
 1.3  2.8   0:01.65 apache2                                                                  
 1.3  2.3   0:00.20 apache2                                                                  
 1.0  5.6   0:00.95 apache2                                                                  
 0.7  2.8   0:00.77 apache2                                                                 

Would you please help me to debug this?

Hello,

There can be a few reasons for this. The fact that systemd-journal is the main process using up your processor could mean your Linode is attempting to write too fast.

To investigate this, you can use the following command:

journalctl

The output of that command should give you a better idea of what the root cause of the problem may be. I hope this helps point you in the right direction!
