zabbix server is not running: the information displayed may not be current

[mounir]

Hello Everyone,

I have been using Zabbix for quite a while and today out of sudden, I start getting the message that says "zabbix server is not running: the information displayed may not be current".
I am familiar with this issue before so already checked the following

zabbix.conf.php --> all fine
zabbix-server.conf --> all fine
SULinux --> disabled
mysql --> can login with same credentials as in zabbix.conf.php file

I am using Zabbix 4.0.5 and this is the output for zabbix-server.log:

Appreciate any assistance on this matter.

Thanks

guys i managed to figure out the issue

by looking at zabbix-server.log

it seems I was using the default CacheSize value which is 8 MB after increasing it and restarting the zabbix-server service it works like a charm.

Thanks anyway

Just increase the CacheSize value and restart the service
