[sr-dev] benchmark rpc commands causing kamailio to crash

hello all today testing kamailio 5.0.1 version we have seen that some rpc commands of benchmark module are not working fine. when trying to change enable_global parameter, setting 1 for example it says that the parameter is invalid /usr/local/kamailio-5.0/sbin/kamcmd -s udp:127.0.0.1:2046 benchmark.enable_global 1 error: 500 - Invalid Parameter Value besides, it also permits to set a granularity value of 0 without giving error. By doing that, if the kamailio has calls in progress, the kamailio get a crash Core was generated by `/usr/local/kamailio-5.0/sbin/kamailio -P /var/run/kamailio/kamailio_talos.pid -'.
