Zabbix server restart fail

[CMD49]

Hi,

Here is my configuration :
Zabbix server 3.4.3 installed on VM Ubuntu 16.04.3 LTS
There is a cron job which restart zabbix-server every 2 hours.

For a month, I have a problem which appear "sometimes".
The problem appears, in general, at the end of the week, at 2pm (can be on friday, or sunday...). The server start is cron job to restart zabbix-server and it never start again. To solve this, we have to restart the OS (then everything runs fine again, till the next crash).

I tried several times to : "service zabbix-server stop" (or "start")... The command never ends.

Having a look in service --status, shows that the service is down.

In zabbix-server.log : there is nothing.
In zabbix-server.log.1 (previous log I suppose) : here is what we have :
30503:20171014:160001.927 Got signal [signal:15(SIGTERM),sender_pid:1,sender_uid:0,reaso n:0]. Exiting ...
30504:20171014:160001.927 Got signal [signal:15(SIGTERM),sender_pid:1,sender_uid:0,reaso n:0]. Exiting ...

30403:20171014:160001.979 Got signal [signal:15(SIGTERM),sender_pid:21327,sender_uid:0,r eason:0]. Exiting ...

Mysql db is working properly.

I'm stuck...
My knowledge of linux is poor, but I tried to check all the logs, and found no interesting informations.

The problem probably begun when I did a "apt upgrade" few weeks ago, but as the problem did not appear immediatly, when I noticed that, I had already remove my snapshot...

Any idea?

Thank's a lot !

Hope....

I finally found a problem like mine here :

https://www.zabbix.com/forum/showthread.php?t=56657&highlight=restart

I then tried to remove the line specified in this post : https://www.zabbix.com/forum/showpos...1&postcount=10

Then I executed then command : "systemctl daemon-reload", then "systemctl restart zabbix-server.service"

And it's seems to have done the job.

My zabbix server has started.
I hope this will stay stable.

Will keep this post updated.
