Hi Daniel,

I tried to compile with memory manager in debugging mode like this:

MEMDBG=1 make cfg 'include_modules= textopsx db_mysql jansson json
snmpstats tls utils uuid'
make all
/etc/init.d/kamailioa stop
make install
/etc/init.d/kamailioa start

But still I'm getting nothing on:

kamailio -I | grep DBG_QM_MALLOC

Any hints?

With kind regards,

Jurijs
