Check your config files for typos....

New to Zabbix - Running into the same problem. Fresh rollout of Zabbix, got alert stating Zabbix Server was not running. Attempted to start service, get error below. What other conf file should I be checking for typos? Also, there are no server log files present.

Thanks

[markfree]

A good way I find to verify the configuration file, is to reverse grep the comments. That might also display some typos that are not commented.

$ grep -v '^#' /etc/zabbix/zabbix_server.conf | grep .

[pcsi88]

Thanks markfree - I ended up dropping the db and rebuilding. Server service is not starting, i now get a message stating its activating.. ??

Once again - thank you very much for the assist.

[Atsushi]

The following message is output in the Zabbix server log.

3199:20230316:122120.724 cannot initialize configuration cache: cannot get private shared memory of size 12884901888 for configuration cache: [12] Cannot allocate memory

Your environment seems to be running out of memory, so try adjusting the CacheSize to a smaller value for your environment.

[hgarzon]

dear

After adjusting the CacheSize to a smaller value it worked !! I will increase the memory of the server, thanks !!

[angelovic]

I was in same situation: Zabbix 6.4 stops to work after I imported over 50 hosts (switches). Increasing of CacheSize fixed it.
