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.

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!

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

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.

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

Hello,
can you try with the patch from commit:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=c737ff95...
It is one line of effective code that you have to change. Let me know if goes ok now and I will backport to stable branches.
Cheers, Daniel

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.

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

Hi Daniel
I've tried the patch on my 3.2.2 and it doesn't crash now!
Thanks! Yufei

Hello,
can you try with the patch from commit:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=c737ff95...
It is one line of effective code that you have to change. Let me know if goes ok now and I will backport to stable branches.

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.

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

Hello,
can you try with the patch from commit:

It is one line of effective code that you have to change. Let me know if goes ok now and I will backport to stable branches.

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

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.':

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.
