Also i found problem with SourceIP parameter in agent configuration. Zabbix agent try bind ipv6 socket with IPv4 address from SourceIP

Comment by Alexei Vladishev [ 2012 Sep 08 ]

What command did you use to generate this output? Netstat?

Comment by gescheit [ 2012 Sep 08 ]

This was output of fstat.

sockstat -l -6 -p 10052

Check patch in attachment. Description:
fix af_type in source address check(if HAVE_IPV6)
zbx_tcp_connect now try to connect to all IP(4 and 6) addresses from given hostname(if HAVE_IPV6)
close socket if unable to bind it(freebsd dont close it) (if HAVE_IPV6)
more debug messages

ipv6 related issues that might be dupes or at least should be considered/fixed together :

ZBX-2568
ZBX-3549
ZBX-3879
ZBX-4252
ZBX-5551
ZBX-6536
ZBX-6591
ZBX-6807

Comment by Vladislavs Boborikins (Inactive) [ 2019 Aug 28 ]

Hello,

Since this version of Zabbix is no longer supported, we've decided not to prioritize this bug for the near future and close the issue with "Won't fix" resolution.

Please let us know if this decision should be reconsidered.

Regards
Vladislavs
