Netdata parent freezes and solution

Q: My Netdata parent is freezing but I don’t see any issue in the logs.

A: You may need to set /proc/sys/vm/max_map_count to 2000000. Netdata uses a lot of memory maps and if you have a lot of children you’ll run out if you don’t set this.

This is true only when you use memory mode “save”, right?
