Hi Charles,

Yes, when I build and run it completely from master, I have the same issue.

So I get this when I shut it down with `killall kamailio`. 
This time I run it with log_stderror=yes , so it prints alot of debugging messages -  it seems it tries to free() un-allocated memory :

........

I use libmemcached version 1.0.17 .
Let me know if I can help you debug this.

Hi Dragos,

I don't think it will make a difference, but do you still see the problem if you build/run Kamailio completely from master, instead of just copying across the compiled memcache module?

Cheers,

Charles

Hi Henning & Charles,

So far the module performed pretty good for us.

But there might be a problem, when I shut down Kamailio I see this in the logs :

ERROR: memcached [memcached.c:255]: mod_destroy(): memory manager callbacks not removed, returned INVALID ARGUMENTS but continue anyway

It also dumps core at shutdown:

Hello Dragos,

just one thing to add - if you find any issues with the master version of the
module, please report to our developer list that we could take a look.

Best regards,
