Re: [SR-Users] kamailio crash periodically in timer handler

Dear Daniel, community, A few days ago I have already uploaded the diff that probably causes a rare crash with kamailio, but as I mentioned, we have another issue as well. Our clients are registered via TLS to kamailio, and we want to change their presence ( to offline) when the TLS connection is disconnected. TLS disconnection is detected properly, location record is removed – but presence is not updated properly on Ubuntu…. It works perfectly with Kamailio 4.2.4 on debian, but does not work on 4.2.4 on Ubuntu trusty. The configuration is the same, network environment is the same. Kamailio is built from source, with a few modifications in ul_publish.c (diff was sent a few weeks ago). We want is that if a tcp socket has broken, the contact’s of the user gets a NOTIFY with closed state. It seems it is generated but the clients do not receive this. Here are some log parts about the NOTIFY: (ERROR logs are DEBUG logs, only for easier separation) --------- May 12 10:44:41 ctdsip3 /usr/local/sbin/kamailio[23221]: ERROR: pua_usrloc [ul_publish.c:341]: ul_publish(): #012EXPIRE type May 12 10:44:41 ctdsip3 /usr/local/sbin/kamailio[23221]: ERROR: pua_usrloc [ul_publish.c:350]: ul_publish(): Building pidf...

-------------------- Could you give any hints how to start the troubleshooting? Is it possible that the issue comes from a system library that is buggy in Ubuntu fine in Debian? Or kamilio is build with different paramters in different OS? Thank you in advance.

Anyhow, as I saw some remark on another email from you, are you using in this config t_suspend()/t_continue()? Can you upgrade to run latest version from branch 4.2, there were some fixes since version 4.2.3, which you mentioned you run. In that way we rule out that your instance is not affected by those issues fixed meanwhile. Daniel On 28/04/15 11:50, Péter Barabás wrote: Hi, here is the svn diff of ul_publish.c attached.

We modified the ul_publish.c source in order to achieve the following results: - when client sends a REGISTER, an implicit PUBLISH is called so in each registration, publication should also happen - when tcp socket is lost, we want that the contacts of the lost user get a presence NOTIFY with open=0 state to show the unregistered (lost) state Here is the ul_publish.c source, maybe the bug is in it. But in our dev system, it works like a charm: [...] it is not easy to review the full file alone. Can you post the diff with your changes (use git diff if you cloned via git or diff -u)? That should be easier to analyze and see if you introduced any issue or is from another place.
