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": " Jun 12 15:19:07 myserver2 /usr/sbin/kamailio[2293]: INFO: drouting [drouting.c:476]: "dr_reload" MI command received!

2. And the second crash on start up (with the bad dr_rules prefix):
" Jun 12 15:20:16 myserver2 /usr/sbin/kamailio[5352]: WARNING: drouting [dr_load.c:577]: no valid routing rules -> discarding all destinations Jun 12 15:20:16 myserver2 /usr/sbin/kamailio[5352]: : <core> [mem/q_malloc.c:440]: BUG: qm_free: bad pointer 0x4 (out of memory block!) - aborting Jun 12 15:20:16 myserver2 /usr/sbin/kamailio[5393]: : <core> [pass_fd.c:293]: ERROR: receive_fd: EOF on 30 Jun 12 15:20:16 myserver2 /usr/sbin/kamailio[5333]: ALERT: <core> [main.c:751]: child process 5352 exited by a signal 6 Jun 12 15:20:16 myserver2 /usr/sbin/kamailio[5393]: DEBUG: <core> [tcp_main.c:3555]: DBG: handle_ser_child: dead child 19, pid 5352 (shutting down?)

Thanks very much!

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
