++ Some graphs not showing/Segmentation Fault ++

It's some form of memory leak. You should run the following then, from the source code directory and after the binary is made:

Code: Select all

gdb ./spine
run -R -V 5

After it segfaults, obtain the IP and then

Code: Select all

b *0x<instruction_pointer_address>

That should give you a line of the code where the program faulted. I'll need that.

Also, give me a "uname -a" and let me know the distribution.

Thank for your suggestion, the result as below:

[root@dragon ~]# uname -a
Linux dragon.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:47:32 EDT 2009 i686 i686 i386 GNU/Linux

Thank you.

Can you do the same and give me the "backtrace"? Also, see if RH has updates to net-snmp. Did you install from an rpm?

----------------------------------------------------------------------------------
When I try command "./spine -C /etc/spine.conf -R -V=5 --poller=1"
I can not find segmentation fault.
If I try "./spine -C /etc/spine.conf -R -V=5 --poller=0"
I can find segmentation fault.
That is cause of the problem of segmentation fault or not ?


Thank you.

Thank you for your support, I already fix the problem.

[TheWitness]

So, what was the problem?
