Comment by Riaan Olivier [ 2014 Oct 01 ]

Okay so after allot of investigation I found the issue to be that the curl had double linking to the libcrypto libraries. Seems to be issue https://github.com/freebsd/pkg/issues/936

ldd /usr/local/lib/libcurl.so

/usr/local/lib/libcurl.so:
libidn.so.11 => /usr/local/lib/libidn.so.11 (0x801264000)

libthr.so.3 => /lib/libthr.so.3 (0x80336a000)
libcrypto.so.6 => /lib/libcrypto.so.6 (0x80358d000)

I had to reinstall curl using pkg upgrade curl, it was originally installed using the port to compile the module.

After the install its correct and the server starts.

Comment by Riaan Olivier [ 2014 Oct 01 ]

Just realised that SNMP support was still disabled, and as soon as I enable SNMP support it crashes.

Comment by Aleksandrs Saveljevs [ 2014 Oct 01 ]

Thank you for the investigation! This issue is the same as ZBX-8733. Seems that there is nothing to fix on Zabbix side, closing.

Comment by Riaan Olivier [ 2014 Oct 02 ]

This issue has the same symptoms but I fixed the installation of curl to only link to one libcrypto library and it's still crashes with snmp. Is there something I missed in the ZBX-8733 that explains what the snmp issue is and why it does not work? Else this is still a Zabbix problem.

Comment by Riaan Olivier [ 2014 Oct 02 ]

The issue is still relevant, because I fixed the curl issue and snmp still does not work? Can you please explain if I missed something, to why you state that its the same issue as the other task.

Comment by Oleksii Zagorskyi [ 2014 Oct 02 ]

Closed as duplicate of different issue report - ZBX-8849.
But symptoms are the same.
