Hi,

I have been running Zabbix with a static configuration for the last month or so but after my internet link went down for 5 days for some reason Zabbix crashed and now it won't start. I was running v1.8.4 on seeing that 1.8.5 was release I upgraded but the issue still remains.

When zabbix_server started it send an email saying that one of the hosts are up, then crashes and when I attempt to start it again it sends one more email and crashes again. It seems to be getting through the list of hosts that are now contactable, but it keeps crashing so I think I probably should file a bug report.

I have attached the objdump if that helps find the source of the issue.

This is the log output when it starts and then crashes:
