Waypoint limit?

Hi,
is there a limit on number of waypoint that can be loaded on arducopter? I tried loading more than 100 waypoints, did not work. Up to 100 yes. When adding some commands for cameratrigger even less than 100, by 75.
I thought there is no limit.
Might it be an issue of the 2.4.6 version and would be solved when using the 2.4.8?

Thank you

There are limits (as memory isn’t unlimited), but it is about 700 waypoints.
