Hi,

I am trying to run a load test of 1000 messages/sec with 3gpp-SMS #### Kamailio details

Kamailio version : 5.7.4 (downloaded from deb repo) Ruuning under Ubuntu 18.04.6 LT PKG Mem 32 MB SHM Mem 1024 MB

When I run the load for around half an hour the PKG mem usgae keeps on increasing and finally after the mentioned (half an hour) time Kamailio start putting Error Logs that : **_could not allocate private memory from pkg pool_**

I referred to https://www.kamailio.org/wiki/tutorials/troubleshooting/memory, and when I use **kamcmd pkg.stats** I see blow out put for the udp receivers : ``` { entry: 1 pid: 11070 rank: 1 used: 3652840 free: 0 real_used: 16777216 total_size: 16777216 total_frags: 0 desc: udp receiver child=0 sock=192.168.136.151:5060 } { entry: 2 pid: 11071 rank: 2 used: 3652840 free: 0 real_used: 16777216 total_size: 16777216 total_frags: 0 desc: udp receiver child=1 sock=192.168.136.151:5060 } { entry: 3 pid: 11072 rank: 3 used: 3652912 free: 0 real_used: 16777216 total_size: 16777216 total_frags: 0 desc: udp receiver child=2 sock=192.168.136.151:5060 }

```

On further enabling **memdbg** for individual packets, I could see that for each message processing : 204 Malloc operations , 184 free operations . _Seems to be a memory leak condition_ . Am i missing something here ?

On matching the allocated and freed address, I could find below source files where address is allocated but not freed : ``` May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:450]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) called from core: core/route.c: route_add(124) May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:540]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) returns address 0x7fc29f2a4188 May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:450]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) called from core: core/route.c: route_add(124) May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:540]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) returns address 0x7fc29f2a4200 May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:450]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) called from core: core/route.c: route_add(124) May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:540]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) returns address 0x7fc29f2a4278 May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:450]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) called from core: core/route.c: route_add(124) May 6 15:23:48 stgn-haud-vm-ub-kamailio01 /usr/sbin/kamailio[14646]: INFO: <core> [core/mem/f_malloc.c:540]: fm_malloc(): fm_malloc(0x7fc29f1fb010, 48) returns address 0x7fc29f2a42f0 ```

Need guidance support here how to avoid this memory leak condition and how to get more details to aid further investigation.

Thank you! Regards Paresh Panda
