> Every time a profile is update, an updatedProfile event is sent and triggers the segment evaluation rule. It's easy to create a segment of all users that are not in this segment, which  will produce an infinite recursion and go into StackOverflowError :
> {code:json}
> {
>   "itemId": "_3a71uuslk",
>   "itemType": "segment",
>   "version": 4,
>   "condition": {
>     "parameterValues": {
>       "segments": ["_3a71uuslk"],
>       "matchType": "none"
>     },
>     "type": "profileSegmentCondition"
>   },
>   "metadata": {
>     "id": "_3a71uuslk",
>     "name": "test",
>     "description": null,
>     "scope": "systemscope",
>     "tags": [],
>     "systemTags": [],
>     "enabled": false,
>     "missingPlugins": false,
>     "hidden": false,
>     "readOnly": false
>   }
> }
> {code}
>  
> Probably other kind of rules can also go into StackOverflowError. We should try to avoid going into this kind of recursion
