+# Critical Analysis of the broker
+
+There are a few things that can go wrong on a production environment:
+
+- Bugs, for more than we try they still happen! We always try to correct
them, but that's the only constant in software development.
+- IO Errors, disks and hardware can go bad
+- Memory issues, the CPU can go crazy by another process
+
+For cases like this, we added a protection to the broker to shut itself
down when bad things happen.
+
+We measure time response in places like:
+
+- Queue delivery (add to the queue)
+- Journal storage
+- Paging operations
+

things to be monitoring when healthy.
