How many calls per second are you routing?
Are you doing something specific beside just routing calls via carrierroute?
Are you running any private modules?

Thanks for the assistance. So far I have not been able
to re-create the problem in the lab but have had the crash with identical back traces
(same location) on 7 different border servers.
More RAM and less children seems to have led to stability but I will still be trying to
recreate the problem and fix the root cause.

Hello,
as it seems to happen in a place that look safe from this point of view,
might be the case of memory corruption (overwrite, double free, ...).
Needs to compile in memory debug mode, guidelines at:
http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory
When run in debug mode, a double free or overwrite is reported in the log.
Cheers,
Daniel

We're using Carrier route with about 53,000
routes stored in a mysql
databse. We're getting this crash in production that we never had in the
lab.
The bt is below. Does anyone have any suggestions?
nline static void free_to_params(struct to_body* tb)
{
struct to_param *tp=tb->param_lst;
struct to_param *foo;
while (tp){
foo = tp->next; <-- **** Line 75 *****
pkg_free(tp);
tp=foo;
}
}
#0 free_to (tb=0x817cf10) at parser/parse_to.c:75
#1 0x080daf70 in clean_hdr_field (hf=0x8a8ee18) at parser/hf.c:182
#2 0x080db05b in free_hdr_field_lst (hf=0x8a905b8) at parser/hf.c:209

Hi Jonathan,
this seems not related to carrierroute, as you can see from the backtrace the
crash is in the parser code. Would be interesting if this is related to some
invalid message, or an unrelated error. Have you tried to replay the message
in your lab that causes the crash, after isolating it from the backtrace?
You should also take a look into the "tp" pointer with the debugger, try to
investigate why it has an apparently invalid value here.
Cheers,
Henning
