Hello, the question is, why such added cron tasks:*/10 * * * * killall -u ilocked*/25 * * * * service apache2 restartЗачем every 10 minutes to destroy all the processes? I have the whole log in the error is reached CZK-tasks view. And Apache why to overload every 25 minutes? Overload? |

Hello. please Wait, the request is sent to the administrator. |
| Answer: |
These tasks are added to reduce the load , because you have hanging processes. if they remove your server again may not be available. while this works and the load on your server is normal and the websites are loaded with normalnya speed |
| Question: |
Now it is clear. But when I asked you about errors in the logs, it was possible to say that the processes are killed. What do you think, can I increase the value from 10 minutes to half an hour or an hour? And is it possible to leave one of the two? overload Apache or the end of the process? |
| Answer: |
when we asked for this decision have not been entered yet. not yet solved the problem with the load it is recommended to leave such limits. even so limits the number of processes increases, sometimes significantly, atk increases the load. it is not normal for drupal ? we have many cliento has sites in drupal and the engine problems did not create. please check more carefully the site settings. |
