Bogdan,

The one I provided is the only one I have with the memory debugging compiled 
in. I’m going to re-enable that and push it so that we will have that info when 
it recurs.

Hi Ben,

DO you have the backtraces from more similar crashes ? may there is a pattern 
there.

Bogdan,

It’s happening every few days, so it is pretty frequent. There was another one 
yesterday but the DBG compile flags had been temporarily removed for that one.

We have not been able to determine a sequence to reproduce it yet.

Hi Ben,

How often this crash happens ? are you able to reproduce it ?

The acc extra should work in the branch route, no problem. Out of curiosity, I 
will try to reproduce you case (timeout -> failure route -> t_relay -> 
branch_route) to see if I can reproduce it.

Bogdan,

Yes, we are setting acc_extra variables in our branch routes, which are 
sometimes (but not always) called from failure route. Are acc_extra variables 
not available for use in branch_routes?

We don’t currently use drop_accounting anywhere in our script. If I call it 
before that branch_route then it will stop accounting for that call, right? We 
need to have accounting records for the call, so I’m not sure how that would 
resolve the issue?

Hi Ben,

Thanks for the info. The crash happens when you try to set an acc extra 
variable in branch route (when a creating a new branch via failure route, on 
timeout).

Now, do you use the drop accounting in your script ? and considering the above 
scenario, it is possible to have the drop acc before the branch route ?

Hi Ben,

The BT indicates a double free for the accounting context - and I noticed you 
use 2.4.1 version. And yes, there was an issue related to acc context, issue 
that was fixed starting 2.4.2. So, could you upgrade to the latest 2.4 and see 
if the crash still happens ? As I think the fix is already there.

Hi Ben,

According to the backtrace, the memory debugger was not activated. Do an 
"opensips -V" to check the resulting compile flags - do you see the DBG_MALLOC 
and QM_MALLOC ?

I was able to compile with those options and the crash has occurred again. 
Backtrace is here: https://pastebin.com/dezi9xUU<https://pastebin.com/dezi9xUU>.

Even though I had `memdump=1` set in my script, there was no extra memory 
debugging information in the logs prior to or at the time of the crash. I’m not 
sure if that is expected or not.

Hi Ben,

You can change the compile flags via the Makefile.conf file - the menuconfig is 
also updating that file. So during your build you can simply push a 
pre-modified Makefile.conf file with the options needed for memory debugging.

Bogdan,

Unfortunately, we have run into a similar issue before. Our build system is 
completely automated and there is no way to inject the `make menuconfig` 
interactive step into that process. If I were to be testing this locally I 
might be able to work something out, but I could never get such a build into 
our testing environment which is where the crashes are occurring.

Do you have instructions for enabling memory debugging that do not require 
using the interactive TUI tool? What does the menuconfig program do when these 
options are selected? Are there some defines or other settings we can change 
ourselves and bypass menuconfig?

Hi Ben,

all the BT's points to crashes while doing memory ops. I suspect a memory 
corruption that randomly triggers crashes in different parts of the code.

Could you try to re-compile with memory debugging support ? See 
http://www.opensips.org/Documentation/TroubleShooting-OutOfMem<http://www.opensips.org/Documentation/TroubleShooting-OutOfMem>,
 the "How to handle it" section.

Subject: OpenSIPS Crash

Hello,

We have been having sporadic crashes and I was recently able to recover a core 
dump for one. I have uploaded it here: 
https://pastebin.com/ABktcYcH<https://pastebin.com/ABktcYcH>.

I picked out a Call-ID from the crash data and took a look in our tracing. I 
have uploaded it here: 
https://pastebin.com/ZEzUUKZ5<https://pastebin.com/ZEzUUKZ5>.

It appears that a downstream server was extremely lagged and failed to respond 
to an INVITE. We sent the INVITE to another server and the call was connected, 
but then eventually the original server “caught up” and sent a burst of 200 OK 
responses. The crash seems to have occurred processing the ACK to one of these 
responses.
