### I do next test, how many memory leak in time each 100 calls in kb:
```
in (is used memory from FREE before and after SIPP command)
first 100 calls (928188-926836)/100.0=13.52
next 100 calls total 200 calls (932564-928188)/100.0=43.76
next 100 after total 300 calls (942832-932564)/100.0=102.68
next 100 after total 400 calls (961088-942832)/100.0=182.56
next 100 after total 500 calls (989580-961088)/100.0=284.92
next 100 after total 600 calls (1030704-989580)/100.0=411.24
next 100 after total 700 calls (1086652-1030704)/100.0=559.48
next 100 after total 800 calls (1159984-1086652)/100.0=733.32
```
### code:
```
cat count_mem_seq.sh
#!/bin/bash
cc=0
while true; do
echo "---------------------------------------- after $cc calls"
free
echo "Presence Kbytes RSS Dirty"
for line in $(pgrep -f '/usr/local/kamailio-dev/sbin/kamailio -f /usr/local/kamailio-dev/etc/kamailio/kamailio.cfg -P /var/run/kamailio_dev/kamailio_dev.pid -m 16 -M 8 -u root -g root')
do
pms=$(pmap -x $line|grep total)
echo "$pms pid:$line"
done
echo "----------------------------------------"
./sipp -nostdin -sf ./uac.xml -p 5099 -s uas -r 2 -rp 1000 -m 100 81.31.45.53:6688 -trace_err -inf ./inf3.csv > /dev/null 2>&1
if [ $? != 0 ];then
exit
fi
let cc+=100
done
```
### output:
```

#### BTW: I try create same BLF presence server with opensip, which not have memory leak, but stop response after call refer.
#### I hope that it`s help.
