Hello!

We have been using Zabbix for the past 1.5 years where memory usage had been constant.  On 06.07. we have upgraded to Zabbix 7 and we also migrated our Postgres to version 16.

After the update the configuration of Zabbix was retained, only modifications were to enable the async pollers. Templates were updated to the lastest version (mostly Linux by agent, Mikrotik by SNMP are used).

On the 19th we have noticed that zabbix was consuming high amounts of memory and was restarted, which made it return to normal levels.

Observing memory of the zabbix_server master process it is obvious it is constantly increasing. The other zabbix processes are non-issue only the master process seem to own this memory as "private".

Zabbix info

No HA, no proxies, DB and zabbix_server co-located on same server with 24gb total memory.

Result:

zabbix_server master process consumes more and more memory.

Expected:
zabbix_server master process to NOT consume more and more memory,
