Product: Anti-Bot, Anti-Virus, URL Filtering  
Version: R81.10 (EOS), R81.20, R82

## Symptoms

- The Resource Advisor (RAD) process **rad_resp_slow** stops working and creates a core dump file in the _/var/log/dump/usermode/_ directory.
- Browsing to Internet web sites becomes very slow.

## Solution

RAD extended flow information is now logged into a cyclic CSV file - _$FWDIR/log/rad_events/rad_flows.csv_. This enhancement provides visibility into RAD connections, helping to monitor and troubleshoot.
