Hello,
this situation seems to be caused by the fact there is no valid routing
rule at all.
Can you get the backtrace? First do:
ulimit -c unlimited
Then run again an a corefile should be generated (in / or in working
directory) - use gdb to get the backtrace:
gdb /path/to/kamailio /path/to/corefile
bt full
Send the output here.
Also send 'kamailio -V' to know exactly your version.
Cheers,
Daniel

Hi Daniel
Thanks for the reply!
I tried it again and the log seems to suggest it crashed when loading
the dr_rules table that contains non-digit prefix, e.g. prefix bing 'abc.':
1. First crash when doing MI command "dr_reload":

2. And the second crash on start up (with the bad dr_rules prefix):

Mill Rd, Saltaire, BD17 7EZ Hi
I'm using drouting module and seems that it only allows digit-only
prefixes. Also all the number of digits to be stripped ('strip' defined
in dr_gateways) must be all digits too. When I used non-digits in these,
Kamailio crashed.
Is there any way in drouting module that I can use prefixes with
alphabet and dots, e.g. "gateway1."? Thanks very much!
iirc, drouting
accepts only digit based prefixes. Alphanumeric keys
are not suitable for tree structures, like used by drouting, because
there will be soo many children for each node that will use lot of
memory.
Anyhow, it should not crash, do you have a backtrace or a log for it?
Maybe you can combine several modules to get you go, if you want to
use drouting. Like using mtree (it has a way to define the characters
allowed in the prefixes -- still not suitable for all the characters)
or htable to map your alphanumeric key to a digit only key. Then you
can use the result with drouting.
Cheers,
Daniel
