zabbix3.0.3 server process exit after mysqld crash

[tristankuo]

version: 3.0.3

i use
watch -n 0.2 "ps -ef | grep zabbix_server"
to watch the process,
then
i stop mysql server,
i watched zabbix server process exit immediately.

the log is:
18282:20160712:141509.782 One child process died (PID:18307,exitcode/signal:1). Exiting ...
18282:20160712:141511.783 [Z3001] connection to database 'zabbix30' failed: [2003] Can't connect to MySQL server on '192.168.13.11' (111)
18282:20160712:141511.783 Cannot connect to the database. Exiting...


But, zabbix2.4.x has no such problem.
in 2.4.x, server process will wait mysql server to startup.


So, i worry about that if network is down for serval seconds, zabbix server 3.0 exits.

Yes, I also confirm that this behavior.
Zabbix 2.4.x has no such problem.

It's a known issue, being fixed.

Did you check from your zabbix server connectivity to DB backend using mysql and telnet command?
