 |
|
Since I have upgraded to net-analyzer/fail2ban-0.9.6, it won't stop or reload: | Code: | # /etc/init.d/fail2ban restart
* Stopping fail2ban ...
* start-stop-daemon: 1 process refused to stop
* Failed to stop fail2ban [ !! ]
* ERROR: fail2ban failed to stop |
It also crashed in the middle of the night last night. If I do 'ps ax', it doesn't show the fail2ban process
Does anyone have any suggestions? |

Hello
If fail2ban process is not running anymore, then you may wish to remove PID file (/var/run/fail2ban...): luckily, that would be enough to be able to restart service.

| The generic way to do that under openrc is `/etc/init.d/service zap` |

| I'm more concerned that this is a recurrent problem. |

| Of course, understood that resolving random service failure is priority. But you have provided no insight as to why the service failed, just that it did. Naturally, that might elicit reply from others who had fail2ban crash, but so far, those people have decided to not participate in this thread. |

| Thanks. I'll keep watching this thread. I've downgraded my installation to the last stable version. |

| If you plan to update fail2ban again, you should have a look into the /var/log/ files (I suppose /var/log/syslog is the right log file), when it crashes. Also, please post the result of the emerge --info" command, to help us understand why fail2ban is unstable for you. |

I'm still having this problem with the latest masked version: 0.9.7.
The init script runs the following when it stops fail2ban: | Code: | start-stop-daemon --verbose --stop --pidfile /run/fail2ban/fail2ban.pid "/usr/bin/fail2ban-client stop"
* Sending signal 0 to PID 5982 ... [ ok ]
* Sending signal 0 to PID 5982 ... [ ok ]
[many more lines the same]
* Sending signal 0 to PID 5982 ... [ ok ]
* Sending signal 0 to PID 5982 ... [ ok ]
* Sending signal 0 to PID 5982 ... [ ok ]
* Sending signal 0 to PID 5982 ... [ ok ]
* Sending signal 0 to PID 5982 ... [ ok ]
* start-stop-daemon: 1 process refused to stop |
Despite this, the pid /run/fail2ban/fail2ban.pid file does not exist, "ps ax" does not show the process and the fail2ban process doesn't exist. The start-stop-daemon command therefore incorrectly reports the process as still running (or times out before it stops).
My system log shows this: | Code: | Dec 10 12:35:42 mypc /etc/init.d/fail2ban[5655]: start-stop-daemon: 1 process refused to stop
Dec 10 12:35:42 mypc /etc/init.d/fail2ban[5636]: ERROR: fail2ban failed to stop

| I met the same behaviour since some weeks, and adding "--retry 20" to the stop command solved the problem. Thank you Frautoincnam for the tip. |
