Interesting that it is same invalid value var=0x3433, but dlg->vars list is ok.
Is v4.1 saving the dlg vars in db?

Yes. It is exactly the same cfg file (I had only to adjust DB tables when moving to to 4.3).

Can you describe a bit when the crash is happening? Like: if you run a stress test, after how many iterations does it happen; what kind of calls are there, between two users or call is forwarded outside to a gateway...

I am load testing simulating transcoding.
There are actually 2 concurrent tests:

sipp simulating user --> kamailio --> sipp simulating gateway refuses with "406 Not Acceptable". This triggers branch to transcoder server
sipp simulating user --> kamailio --> sipp simulating transcoder (200 OK)

sipp simulating gateway calling user --> kamailio forwarding call to gateway -->  sipp simulating gateway refuses with "406 Not Acceptable". This triggers branch to transcoder server
sipp simulating gateway calling user -->  kamailio --> sipp simulating transcoder (200 OK)

Here are the last number of calls based on acc_cdrs after crash:

mysql> select count(*) from acc_cdrs;
+----------+
| count(*) |
+----------+
|   168623 |
+----------+

mysql> select count(*) from acc_cdrs;
+----------+
| count(*) |
+----------+
|   221434 |
+----------+

mysql> select count(*) from acc_cdrs;
+----------+
| count(*) |
+----------+
|   244369 |
+----------+

mysql> select count(*) from acc_cdrs;
+----------+
| count(*) |
+----------+
|   150870 |
+----------+

If you need it, I can send you the kamailio.cfg privately (I cannot make it public because it belongs to the company I work for).
