** [tickets:#719] AMFD: Invalid read when deleting a node from a node group**
**Status:** review
**Created:** Wed Jan 15, 2014 05:35 AM UTC by Gary Lee
**Last Updated:** Tue Jan 28, 2014 06:17 AM UTC
**Owner:** Gary Lee
When deleting a node from a node group, valgrind sometimes reports an invalid
read.
Possible solution:
Ensure we don't try to read beyond our array, if the removed node happens to be
the last element in the array.
