Hello,
the following log message:
Nov 13 17:29:37 lasola /usr/sbin/kamailio[3536]: DEBUG: <core> [mem/shm_mem.c:235]: shm_mem_destroy(): destroying the shared memory lock
indicates that Kamailio is shutting down already. Can you check up in the logs and see if there are other error messages?
Do you have /var/log/kamailio folder with appropriate permissions so kamailio can create fifo file/etc.?
Cheers,
Daniel

SebastianBest Regards,I'm too bad in reading code, so I don't know what I have to do to get this message go away. The part of the code, where this is printed, changed a bit, but the conditions for printing the message stayed the same. I'm out of ideas what to check anymore.I compared the startup behavior between 4.1.3 and 4.3.3, and in 4.1.3 we had it pretty late in the init section, so there were a lot of modules loaded before tls and it worked without a problem.I tried finding out, when those messages are written to the log. The first one with "no engine available" comes from main.c, if it wants to initialize tls but the module is not loaded yet. But it comes only, if tls_disable is not set. So at this point, Kamailio knows that we want to use TLS. But when this message appears, Kamailio sets tls_disable to 1. The second message "tls support is disabled" comes from the tls module, and only when tls_disable is set. So that's quite logical, because it was set this way before.Hi Daniel,I just moved the TLS config lines up top even before sl and tm module. Also moved the modparam stuff up there. When starting, Kamailio says, it is listening on a TLS socket, but netstat says, it isn't. It's basically the same behavior as before. (This is the last log line from shutting down and the very first lines when starting up.)

Hello,
it could be related to the fact that a lot of internal things are initialized when the first modparam is found in config, but I thought that change was done in 3.x.
Can you put the tls module config part being the first? The other modules don't need to be initialized before, actually tls needs to be initialized and it does some of its init stuff when it is loaded (unlike the common to do init stuff in mod init).
Cheers,
Daniel

Okay, then the message right at the beginning probably just irritated us. But as you can see, we have set enable_tls=1 (previously and in the documentation it was set to 'yes'), but it still doesn't get enabled.
Any more ideas?
Best Regards,
Sebastian

After starting up, kamailio listens on port 5060, but not on port 5061. In version 4.1.1, this config worked without a problem.
Has anybody seen this before? the tls module is there and available, it doesn't say anything about "cannot load module", and it is only a warning message. I'm also wondering, why this message is the first after starting the server. From config I would expect that sl, tm and all the other modules should be initialized before tls.
Best Regards,
Sebastian
