(fault address obviously depends on function called). zabbix_agentd on FreeBSD doesn't fail (returning proper value or ZBX_NOTSUPPORTED). |

Marcin, could not reproduce the issue. Could you please provide the log file with LogLevel=4 from the Agent? |

Fixed/available in dev branch: svn://svn.zabbix.com/branches/dev/ZBX-4059 Thanks, Marcin, for the logs, the cause was an overflown buffer. |
