I have the same issue

With the exact same warning message hanging there, with the exact same Age.

I dug into this and I had a very strange trigger entry in the database:

 triggerid │   expression   │                description                 │ url │ status │ value │ priority │ lastchange │ comments │ error │ templateid │ type │ state │ flags 
───────────┼────────────────┼────────────────────────────────────────────┼─────┼────────┼───────┼──────────┼────────────┼──────────┼───────┼────────────┼──────┼───────┼───────
     12201 │ {11201}>150000 │ icmpOutRedirects on {HOSTNAME} is too High │     │      0 │     1 │        3 │          0 │          │       │            │    0 │     0 │     0

So I set the status value from 0 to 1 so it does not appear anymore in the list.
I do not even know from which template this is ...

Thank you!
