Proxy failing to accept active agents

[highpeak]

Proxy: 5.2.5 psql
OS: ubuntu 18.04

Since the upgrade, at random intervals I sueendly see the below entry in the Zabbix proxy log. The IP listed (172.16.8.27) is the IP of the zabbix proxy.

From this point on, all active agent updates are rejected.

Hello did you able to solve issue?

[highpeak]

I’m afraid I didn’t. I ended up splitting the proxy into two and applying a regular reboot schedule which has prevented a recurrence. But I don’t know what the root cause was.

Hi

I managed to fix this error in my zabbix proxy just enabling the parameter "StartTrappers=17" in zabbix_proxy.conf and restarting the service.
