The issue is trivial to reproduce.  I didn’t test every dialplan module function, but it occurs with both dp_transalate() and dp_match().

 

I’ve opened an issue in GitHub:  https://github.com/kamailio/kamailio/issues/3851

I’ve just noticed a similar behavior in kamailio 5.8.1 after upgrading from 5.6.3.  I haven’t had time to poke around on it much yet.  Wondering if anyone found the root cause?  In my case I’m calling just `dp_match("1", "$rU");`

 

I’ll try to update with a simplified scenario, etc.

I've tried setting corelog=L_INFO but I can still see the WARNINGS.

 

Also, one correction in my previous msg, I don't have 2 "debug" lines, I have them defined within a condition:

 

#!ifdef WITH_DEBUG
debug=L_DBG
#!else
debug=L_NOTICE
#!endif

...

...

It happens after running dp_translate().

 

These are my settings:

 

debug=L_DBG
debug=L_NOTICE
memdbg=L_INFO
memlog=L_INFO
corelog=L_ERR
mem_summary=12
log_stderror=no
log_facility=LOG_LOCAL0
log_name="csbc"
log_prefix="{$mt $hdr(CSeq) $ci} "
mem_join=1

 

 

Any ideas?

 

Thanks, 

Joel.
