Our code is no longer doing database access so this issue will not occur with anything > 2.0. Issue was filed only for reference. |

by the way the CLONE { ... } above suggestion did not work. Look into https://github.com/alandekok/freeradius-server/blob/master/doc/bugs [^] for more in-depth FreeRADIUS troubleshooting. |
