Asterisk crashes on voice activity

Asterisk Asterisk Support
1

I have been struggling getting Asterisk realtime up and running for almost 2-weeks now, after 2 weeks I have almost all errors resolved. This is my first realtime setup that has been tough due to lack of documentation on the database aspects.

Each time a call starts, it rings but as soon as the receiving party picks up Asterisk crashes and it exits me out of the terminal. As I mentioned I have almost all errors resolved, I don’t believe it is connected to the issue but I will mention it in the interest of full disclosure. Most issues were related to database information rather, the sole remaining error is on 1 user/extension only, a warning appears on registration that the user does not have a mailbox however it does. No other users have this error and the config is identical in the voicemail database.

I am running asterisk 1.8.21.0 running with mySQL on a VPS running Ubuntu 12.02.2 LTS that has 1GB Ram and an Intel Xeon E5-2670 2.6GHz processor. Not an ideal environment however I have run Asterisk successfully (without realtime) on worse environments. I was advised on this environment to run a 32-bit version regardless of the processor being 64-bit, I have started from scratch on a 64-bit environment and the same issue occurs.

I have run a backtrace on the core dump according to the wiki article “Getting a Backtrace” but I don’t fully understand it and am hoping someone can help me to diagnose the issue.

Thanks in advance - the output from each step in the instructions is below.

You have a memory corruption problem. As it is so repeatable, you should run under valgrind (there should be documentation somewhere - it used to be in the source tree, but I think that has all moved to the wiki).

Otherwise, all you can do is look to see if there are any warnings in the minutes leading up to the crash, as the crash will be a secondary failure. Building with thread debugging enabled may help get good diagnostics.

Thanks for that David, I really appreciate your quick response.

I will have to get onto this a bit later in the afternoon as it is my son’s birthday party today and we are just leaving to set up the space.

I will keep you posted… again I really appreciate the quick help.

Have a great weekend!

I ran valgrind however I am not confident I understand the problem or how to resolve it. When I look at the output it appears there is something in Ubuntu that hasn’t started or didn’t correctly initialize, secondly it looks like there is a problem in a module, based on the reference in the file made to “switch” I believe this is to do with realtime. I am guessing that whatever isn’t running on Ubuntu is causing the following problems?

As I’m not certain that I correctly understand the output, I have pasted it and all “offending” code blocks referenced in valgrind.txt, could someone please give some direction to where to start to resolve this?

Thanks a lot, again!

The first file I could actually find (starting at the top and working my way down) is “loader.c” where the error seems to occur at line 891, that code block starting at line 890 is:

#ifdef LOADABLE_MODULES
                if (!(mod = load_dynamic_module(resource_name, global_symbols_only, resource_heap))) {
                        /* don't generate a warning message during load_modules() */
                        if (!global_symbols_only) {
                                ast_log(LOG_WARNING, "Module '%s' could not be loaded.\n", resource_name);
                                return required ? AST_MODULE_LOAD_FAILURE : AST_MODULE_LOAD_DECLINE;
                        } else {
                                return required ? AST_MODULE_LOAD_FAILURE : AST_MODULE_LOAD_SKIP;
                        }
                }
#else
                ast_log(LOG_WARNING, "Module '%s' could not be loaded.\n", resource_name);
                return required ? AST_MODULE_LOAD_FAILURE : AST_MODULE_LOAD_DECLINE;
#endif
        }

The next line referenced is 1008, that code block is

        /* first, add find and add modules to heap */
        AST_LIST_TRAVERSE_SAFE_BEGIN(load_order, order, entry) {
                switch (load_resource(order->resource, global_symbols, resource_heap, order->required)) {
                case AST_MODULE_LOAD_SUCCESS:
                case AST_MODULE_LOAD_DECLINE:
                        AST_LIST_REMOVE_CURRENT(entry);
                        ast_free(order->resource);
                        ast_free(order);
                        break;
                case AST_MODULE_LOAD_FAILURE:
                        ast_log(LOG_ERROR, "*** Failed to load module %s - %s\n", order->resource, order->required ? "Required" : "Not required");
                        fprintf(stderr, "*** Failed to load module %s - %s\n", order->resource, order->required ? "Required" : "Not required");
                        res = order->required ? -2 : -1;
                        goto done;
                case AST_MODULE_LOAD_SKIP:
                        break;
                case AST_MODULE_LOAD_PRIORITY:
                        AST_LIST_REMOVE_CURRENT(entry);
                        break;
                }
        }
        AST_LIST_TRAVERSE_SAFE_END;

Then the final line referenced is 1079 that is blank in loader.c, the line above is

AST_LIST_LOCK(&module_list);

Then in asterisk.c on line 4024 the code is

        if ((moduleresult = load_modules(0))) {         /* Load modules */
                printf("%s", term_quit());
                exit(moduleresult == -2 ? 2 : 1);
        }

I have identified an error in the kernal, unfortunately it is much faster and easier for me to just wipe the install and start fresh. I’m sure there is a better way but by the time I have researched it I’m sure I would have done the job.

I will try to keep all updated if the bug re-appears after the re-config or not. Thanks again for your help.

Regards,
Ryan

OK, that didn’t work, I just finished the install, tested and Asterisk crashed again. This time the kernal is fine so that was not the cause.

Something a little different I have noticed on this install however, when Asterisk crashes, rather than going from the CLI to the last active directory, it goes to the /usr/src/asterisk-1.8.21.0 folder that the install was made from.

I would really appreciate any further direction that anyone may be able to provide on this issue.

Thanks,
Ryan

This needs to be taken to issues.asterisk.org/jira/, or at least to the developer mailing list.

Do make sure that you do not have any old modules in your Asterisk modules directory, firt.

So I have found the cause of this problem and have been able to solve it. In a nutshell, the VPS is run by Linode who run 64-bit processors on all equipment, there are recommendations from Linode to run as much as you can on 32-bit installs to reduce the CPU requirements.

It is easy to get Asterisk without realtime running on either 32-bit or 64-bit installations on Linode but, as soon as you enable the mySQL modules on the 32-bit install and complete the config Asterisk crashes as soon as voice hits the line.

I then read a comment that bugged me for the last couple of days, Linode compiles some of their packages only on 64-bit installs with GCC. So I restarted with a 64-bit install of Ubuntu 12.04, configured everything and now no crashes.

The new problem that I believe MAY be related is I now get no sound. Does anyone have any tips on this? I have put in place slightly modified firewall rules from VoIP-Info.org that are as follows:

# SIP on UDP port 5060. Other SIP servers may need TCP port 5060 as well
-A INPUT -p udp -m udp --dport 5060 -j ACCEPT

# IAX2- the IAX protocol
-A INPUT -p udp -m udp --dport 4569 -j ACCEPT

# IAX - most have switched to IAX v2, or ought to
-A INPUT -p udp -m udp --dport 5036 -j ACCEPT

# RTP - the media stream
# (related to the port range in /etc/asterisk/rtp.conf) 
-A INPUT -p udp -m udp --dport 10000:20000 -j ACCEPT

# MGCP - if you use media gateway control protocol in your configuration
-A INPUT -p udp -m udp --dport 2727 -j ACCEPT

Thanks for your help

The no audio problem was due to the firewall rules on the router being used. The install is working correctly now.
