Hi All,

I get the below error.

[zabbix_db] failed: first network error, wait for 15 seconds

But postgres database is up and running.
Can someone help me to fix this issue.

And also the que is growing high SNMPv3

I have attached 2 image of high queue.

Post your Zabbix internal process busy % graph here.

What zabbix version?
What db backend?
Seperate servers or same instance?

Have you checked to make sure you're not running into any limits on the number of connections postgres allows (e.g. max_connections set to 10, zabbix tries to open connection 11 => fails, gets this error)?
