RADIUS server is dumping core

[ramakrishna]

Hi,

I am using FreeRADIUS 2.2.0. Recently I have observed that RADIUS server is
generating core frequently. I have tried debugging the core file using gdb.

Please find the attached file for the gdb output for one of the core file
generated.

Please lemme know if you need any more information for tracing the core
dump.

Thanks,

Core was generated by `radiusd -f'.
Program terminated with signal 10, Bus error.
