we are using 'Apply Rate Limit' on most of our policies. Following are the values set, please also see the screenshot attached.
- Max Req per sec - 100 ( Cluster Wide and Spread limit over checkboxes unchecked)
- Limit each - user or client IP ( selected)
- When limit exceeded - Throttle and **** for 5 sec
- Max concurrent req set to - 100
We are experiencing black out ( service unavailable 503 responses) even though 100 request per sec threshold has not reached
SSG.log extract below

Is anyone able to advice why we are experiencing black out please?
