Hi,
did you check the return value of pfDelete?
should be TRUE, FALSE or -1 (lol) depending on the success, that might
clarify
what is going on. See the pfDelete man page.

But in fact, i experienced a similar behaviour when deleting a group
node.
It said it was deleted successful, then later, i suddenly got an error
saying that my already deleted node had a ref count > 0 and the
application crashed.
Still don't know what happened. Maybe somebody else could clarify the
pfDelete behaviour.
To me it behaves different then in the documentation...
