 Description   

Hi,

I have 2 servers : Database and application.
I don't know why my 2 servers zabbix has memory full since several weeks.
I see with top but i can't find.
I emptied the cache with : sync; echo 3 > /proc/sys/vm/drop_caches and reboot / shutdown.
But it's not OK.

I can't touch Zabbix, It appeared one day.

Can you help me please ?

Hello Mr Saint-Etienne Geoffrey,

Thank you for the screen. Apparently, I don't see a problem here. You have ~5GB free on the backend server. For the database, it is required to add more RAM.

I will close this ticket now, but yes, it may be a bug. If the problem is persistent I would need to ask for the snapshot in the time where the problem is on fire. In this case please attach:
1) zabbix_server.conf
2) zabbix_server.log
3) graphs from Monitoring -> Graphs -> Zabbix server, "Zabbix internal process busy %", "Value cache effectiveness", "Zabbix cache usage, % free", "Zabbix data gathering process busy %"
4) Please elaborate: do you use any external scripts or custom items in your monitoring?

Kind regards,
