Zabbix Server Crashing

[rohirrim]

Hi guys,

I'm using Zabbix 5.4.3 and my database is Mariadb 10.3.31
When I adding a IIS template my vm Zabbix is crashing and when I unlink the template it's keep going work.

Is ıt bug or am I doing wrong anything?

This log is zabbix-server

34515:20210814:221027.411 [file:dbconfig.c,line:102] __zbx_mem_realloc(): please increase CacheSize configuration parameter

Hi,

Thanks for reply.
I see this one but, how is effect my database? When this is happen, my galera cluster is crashed with every node.

When I post this error I start a new db(standalone mysql) and I configure cache size (2GB). I will try this config for old database(galera cluster).

Do you have any suggestion for zabbix config? I have 200 host and it looks like it will increase.

The "CacheSize configuration parameter" in this error message is the Zabbix server configuration.

Thanks for reply.

Yes, it's about the CacheSize problem. I change the line 2GB and it's work right now.

Thanks.
