Cacti & FreeBSD 6.x

[m00h]

Hello,

Since a few days i'm using Cacti on many FreeBSD 6.x host. Since i've migrated to the 6.x branch i got weird problems with Cactid.

When lauching Cactid i've got :

Segmentation fault: 11 (core dumped)

If i look at the Core file itself:

Then :

1 Thread 0x8061800 (runnable) 0x32312032 in ?? ()

Is there any change in the lib pthread ? It seems that Cactid Core dump when trying to create a new thread ? Is there someone using FreeBSD 6.x who can confirm this ?

I'm running:

cacti-0.8.6h_42
cactid-0.8.6.g

Thanks,

Nico

I had the same problem. Segfault on cactid on 6.1

Is this a release version or the SVN version? If not the SVN, can all of you test in that environment? Can I have access to any of your systems to nail down the location of this problem?

Hello,

For me it's the version in the ports (Because of production). I can try any versions if needed. For access it may be possible to do something if it's for debugging purpose.

Cheers,

Nico

I'm getting the SVN version and try to see if something goes wrong or not. It will give an idea on whats going on i believe ..

Cheers,

Nico

[m00h]

Same thing with the SVN version ... i've tried the 3 versions and go some troubles .. Two are doing core dump and the other one does not compile.

[TheWitness]

Can you attach the core file to this thread. Thanks!!

Hello everyone. I came to this forum `cause I have some problems with graphs.
But may be I can suggest something.
I have FreeBSD 6.0 amd64. Today I`ve successfully install
cacti-0.8.6h_42 &&
cactid-0.8.6.g
Everything works fine. I just wonder how you installed php. Have you installed php4 and php4-extensions from /usr/ports/lang? And what are the configure lines (options) to those packages you applied? I have a thought that the Segmentation fault error may be caused by wrong set of extensions or something.

Best regards.

[m00h]

Hello,

The file is quite too big and phpBB doesn't like it
You can get it here http://star.noc.ip-man.net/cactid.core

Cheers,

Nico

[m00h]

You can install PHP Extensions one by one (if you know the extension name) of with the port php4-extensions (/usr/ports/lang/php4-extensions/).

Cheers,

Nico

[m00h]

Hello,

Some news regarding this problem ?

Cheers,

Nico

Please post your cactid binary to the same web site and provide a link. I now have a FBSD VM setup to interpret the core file.
