 Description   

Hello!

We have windows 2016 server installed recently, so we are still rebooting it sometimes and we found that after reboot server stops gathering data from it.
btw, agent version is 3.4.0.

Server was rebooted here:
21054:20170823:160442.081 Zabbix agent item "agent.ping" on host "endor" failed: first network error, wait for 15 seconds
21083:20170823:160815.577 resuming Zabbix agent checks on host "endor": connection restored

connection was restored after some time, but at 16:12 we rebooted windows server again, but there is no info about connection loss at zabbix server log, there is no trafiic from server to client , as I can see using tcpdump, agent works:

[root@zabbix zabbix]# zabbix_get -s endor -k agent.ping
1
[root@zabbix zabbix]#

Now it is 16:22, still no requests from server to agent....

Looks like bug.

btw, last data
Agent ping 23.08.2017 16:08:15 Up (1)
