I'm truly baffled now. To make the changes I used the iRule editor, but after some time I noticed that the errors I was seeing when I ran load sys config verify in TMSH the changes weren't reflected in the error message.

Eventually I made the changes via the GUI and suddenly the verification passed.

To make it even more interesting, a couple of other rules also caused the same error message and I had updated those as well (added braces) via the iRule Editor. Those also kept showing with errors when I ran the verify command, but after I saved that one iRule in the GUI all of them suddenly passed.

iRule Editor problem?
