Hi，
When the busctl command is used to call the method corresponding to this function, the memory used by the process will increase after 65 ~ 70 times. If continue to call, the memory usage will continue to increase.
Refer to the method in SYSTEMd. (such as: ListUnits, GetDynamicUsers)
Thanks,
Byron

Dear all,When using sd_bus_process() + sd_bus_wait() to implement the application(Service), call the methods function on the service can obtain the correct information. Run a certain number of times will lead to insufficient memory and memleak does occur.It should not be a problem with the DBUS method, because a single call does not increase memory, it needs to call the method 65 ~ 70 times, and you will see the memory increase. After stopping the call, the memory will not decrease. It seems that it has nothing to do with the time interval when the method is called.code implementation：int main(){......r = sd_bus_open_system(&bus);...r = sd_bus_add_object_vtable(bus, ......);......r= sd_bus_request_name(bus, "xxx.xx.xx.xxx");......for( ; ; ){r = sd_bus_process(bus, NULL);.......r = sd_bus_wait(bus, -1);......}sd_bus_slot_unref(slot);sd_bus_unref(bus);}thanks,Byron
