You have to try to get a core file. Set core file limits to unlimited:
```
ulimit -c unlimited
```
Then you may need to run kamailio as root and then reproduce the issue to get a core file,
once core file was dumped, grab the backtrace for gdb, see:
- https://www.kamailio.org/wikidocs/tutorials/troubleshooting/coredumpfile/

You need to install debug packages to repeat GDB analyze.
```
dnf install kamailio-debuginfo
```

Do you have any private modules? If not, can you create a minimal kamailio.cfg that can be
used for reproducing?
Do you process the SIP OPTIONS keepalives via event routes or the replies via reply routes
in any way?
I have dispatcher keepalive enabled in many 5.8.x instances and not experiencing any
crash.

No private module.
The current kamailio.cfg is running under rhel 7/kamailio 5.0 with million requests per
day and without any errors.
It seems that if migration process (=> rhel 8 / kamailio 5.8) fails it is related to
dispatcher module changes (attrs_avp, dst_avp...no longer available).
I am not able to respond to the question "Do you process the SIP OPTIONS keepalives
via event routes or the replies via reply routes in any way?"
Here is my dispatcher.list file:

Some lines commented out for 5.8 version.
I will try to build a simplified kamailio.cfg to reproduce the issue.

A small cfg to reproduce it would be indeed great. Regarding the mentioned AVP topics, you
need to migrate them to the new XAVP infrastructure. Have look to the module readme for
the parameters and examples.

Do you have tls enabled? If yes, be sure that you set `tls_threads_mode = 2`, see more:
- https://www.kamailio.org/docs/modules/devel/modules/tls.html#tls.notes
- https://www.kamailio.org/wikidocs/cookbooks/devel/core/#tls_threads_mode

Hi all,
Thanks for your returns.
Yes tls is enabled. I will check for tls_threads_mode parameters.
I'm starting to identify the origin of the problem.
When kamailio starts, the following script part is executed.
#######################################################################
event_route[htable:mod-init] {
$var(propertyName)=PROP_MMM_NODE_PATH;
if (!route(SHOWPROPERTY)) {
# check that all declared nodes are found in node table
$var(i:inx)=0;
while ($var(i:inx)<$(var(propertyParams){param.count})) {
$var(paramName)=$(var(propertyParams){param.name,$var(i:inx)});
$var(paramValue)=$(var(propertyParams){param.valueat,$var(i:inx)});
if (ds_select_dst($var(paramValue),"4")) {
while (is_avp_set("$avp(dsdst)")) {
xlog("L_NOTICE", " " +
"$var(propertyName)[$var(i:inx)] node=$var(paramName) path=$var(paramValue):
$avp(dsdst)");
# remove head of avp(dsdst) list
avp_delete("$avp(dsdst)");
}
} else {
xlog("L_WARN",
"$var(propertyName)[$var(i:inx)] node=$var(paramName) path=$var(paramValue) - no
dispatcher.list entries");
}
$var(i:inx)=$var(i:inx)+1;
}
# remove all avps created by ds_select_dst calls
avp_delete("*");
}
}
#######################################################################
The script runs correctly but at the next SIP OPTION managed by disptcher, there is a
crash.
I think that the use of avp_delete is no longer adapted to the new dispatcher module. This
was not a problem in 5.0
This initialization part is not really useful in our case, I will delete it and check that
the rest works correctly.
Regards
Philippe Gravet
