Radius 3.0.12 crashes on mysql DB conection failiure

Hi all, I am using freeradius version 3.0.12 with rlm_perl module and using mysql with it. When there is connectivity issue with mysql DB or it is unavailable my radius gets crash and i am getting following error. Sat Oct 1 15:04:35 2016 : Debug: (1) perl: perl_embed:: module = /usr/local/etc/raddb/mods-config/perl/example.pl , func = authenticate exit status= All data sources failed! at /usr/local/share/perl5/DBD/Multi.pm line 367. I also tried to catch this error using TryCatch module but it failed. Regards Feroze
