It needs to edit lib/kmi/Makefile and enable system malloc, recompile
and reinstall.

When I added 180K records in the database, I got the "no more pkg mem"
error again.
I increased again:
#define PKG_MEM_POOL_SIZE 32*1024*1024
This allowed me to execute pdt_list with 180K records loaded.
I increased database record count to 240K and got the "no more pkg
mem" error again.
So I don't think it is prudent to just keep increasing
PKG_MEM_POOL_SIZE. Is this an architectural limitation with fifo
pkg_mem, shouldn't this be a dynamic allocation if it's not within
shmem and has no affect on core sip-router function? While the
pdt_reload and pdt_list is going on (takes a few seconds to load and
list), I don't see any problems with the sip-router executions. I
guess I can just use the old fashion database query to look up routes
instead of fifo pdt_list.
Hi Jr,
if you don't use the PKG_MALLOC MM in your system at least the kamailio 1.5
will fallback to the system malloc, which don't have this size restrictions.
For 3.x/ sr there is an option to build the MI interface with system malloc as
well, it this commit:

lib/kmi: option to build it with system malloc
- MI lib can be built independently of core with system malloc for pkg
memory (see Makefile)
Both workarounds should help in your case.
But you're right, its probably more meaningfull to just execute a DB query
instead of trying to pipe all this data through your (productive) sip server.
Regards,
Henning
