Hello to all!

There is a problem with the zabbix agent. When i add the value 0.0.0.0 to the config for ListenIP as:

ListenIP=0.0.0.0 (to exclude IPv6)

The agent sometimes failed to start with the following error:

listener failed: zbx_tcp_listen() fatal error: unable to serve on any address [[0.0.0.0]:30050]

but the netstat shows no 30050 ports used.

it can be fixed temporally by the host restart, but then it appears again.

Here is the config:

PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=**.*.*.**
ListenIP=0.0.0.0
ListenPort=30050
StartAgents=1
Include=/etc/zabbix/zabbix_agentd.d/*.conf
TLSConnect=cert
TLSAccept=cert
TLSCAFile=/etc/zabbix/zabbix_ca_file
TLSCertFile=/etc/zabbix/server.crt
TLSKeyFile=/etc/zabbix/server.key

after deleting string ListenIP=0.0.0.0 the problem is gone, but i need to disable IPv6.

debian 7 (wheezy)
zabbix-agent 1:3.2.3-1+wheezy amd64 Zabbix network monitoring solution - agent

Any ideas?
