Re: [SR-Users] Question about debugging using `kamcmd pkg.stats`

Hi Lucian, the mem_join is enabled by default -- I checked from 4.1.x to 4.3.x. In the Makefile.defs should be a: C_DEFS+= -DMEM_JOIN_FREE In 4.4 I just noticed it was lost when I added the feature to select the memory manger with command line option -x. I will fix it. Even MEM_JOIN_FREE is enabled at compile, you still need mem_join=1 in your configuration file (the default value is mem_join=0). Also, you can change the value for mem_join at runtime, via kamcmd/rpc commands.
