Hey Daniel, Yes, this can be reproduced. I have uploaded the xml and Kamailio log and core files to the following ftp site. Username: Kamailio Password: 99Teaz URL: ftp://ftp.intouchhealth.com Steps for reproducing the crash: Use the xml(rls.xml) to be inserted in the xcap table using a xcap_server with the help of a http client. The service uri is sip:rls@<domainName<sip:rls@%3cdomainName>> in the file. Create subscribe using the service uri in the request line method using SIPp or some SIP client program. (please refer to rls_crash.pcap file). Kamailio crashes as soon as the subscribe is being processed. For the convenience of testing, I had disabled authentication for the Subscribe method.

Maybe you can host it on an website for download or send parts of the log, the last messages before the core message. Also, compressing it in such case is better. Keep memlog and memdbg higher than debug, all the memory operations are not relevant unless they are required by a developer for troubleshooting.

I was using Kamailio with integrated presence, xcap, registrar, rls, sip proxy. I have implemented Kamailio as an standalone SIP presence server with rls and xcap_server. This seems to make it work without crashing. Now I’m unable to recreate the crash.

When you are in gdb, can you do the commands: frame 1 p slb and send the output here. I assume you are using latest 3.2.x, so frame 1 shows that line 1033 in subscribe.c from presence module is executed, which is a function from sl module API.
