Any idea why frames 1 and 2 don't have the symbols? Was there a single core file, presuming the options for core files per pid was set?

No idea, per-process core file is enabled too.

Can you do:

  • frame 4
  • list
  • info locals

The code in branch 4.4 for dlg_handlers.c:1350 is:

			LM_WARN("inconsitent dlg timer data on dlg %p [%u:%u] "
				"with clid '%.*s' and tags '%.*s' '%.*s'\n",
				dlg, dlg->h_entry, dlg->h_id,
				dlg->callid.len, dlg->callid.s,
				dlg->tag[DLG_CALLER_LEG].len, dlg->tag[DLG_CALLER_LEG].s,
				dlg->tag[DLG_CALLEE_LEG].len, dlg->tag[DLG_CALLEE_LEG].s);

So no strlen() to be used there.

This is the NGCP version of 4.4.5
sources at https://github.com/sipwise/kamailio/tree/mr4.5.4 but be aware that list of patches are at https://github.com/sipwise/kamailio/blob/mr4.5.4/debian/patches/series
and I changed the sensible data from the paste

In order you to see the source easily I pasted dlg_handlers.c already patched at https://paste.debian.net/926240/

So no strlen() to be used there.

but the strlen() is coming from syslog()

I would say the problem is dlg is gone from memory when trying to use the string

Did you put in pastebin the wrong file (like dlg_db_handlers.c)?

All the tokens provided by kamailio in that log message are by length and pointer (%.*s), so there should be no strlen done on the pointers we set, so not sure on what syslog can do the strlen and crash.

I wonder if there is a copy/paste issue or the dlg is printed twice by info locals:

event = 10498440
dlg = 0x7fad74f20258
ttag = {
  s = 0x9aabed <buf+557> "0FC4E4CA-58E4A7D4000A8034-123E3700\r\nCall-ID: 3A477FD70434C083@10.10.10.18\r\nCSeq: 5709 BYE\r\nProxy-Authorization: Digest username=\"1111111111\", realm=\"sip.local\", nonce=\"WOUBrFjkp9Qj4YjEwa9jvelH"..., len = 34}
h_id = 854147520
dlg = 0x7fad00000000

After event and at the end. First looks like a valid value, second a bit more strange.

Can you get in the same frame:

p dlg
p *dlg

Is it possible that there is a time consuming operations for BYE (eg, a slow database operation -- accounting or something else) that can take more than 5 seconds?

more than 5 secs? I don't think so. @apogrebennyk can you confirm?
