Hello,
I have a zabbix proxy configured in active mode which send data to remote Zabbix server. However periodically Zabbix Proxy is not able to send data to Zabbix server and in the log file i get the following message
cannot send proxy data to server at "zabbix.server.hostname": ZBX_TCP_READ() timed out
Here is trace of data sender process:
