segmentation fault freeradius 2.1.7 using rlm_sql

[Amir Tal]

Hi all,

freeRADIUS version 2.1.7
(package freeradius2 on centos 5.6)

Radius is configured to store user info (auth) in ldap - running on same machine as freeradius,
and use rlm_sql for accounting info (and simultaneous use checks) - running on remote machine.

For some unknown reason radiusd keeps getting segmentation faults, every few days and even after several hours of work.

Jul 27 04:01:03 RADIUS4 kernel: radiusd[29903]: segfault at 00000000000000c8 rip 00002aef39fb9cfb rsp 00000000456d6170 error 4

Last lines in the radius.log :

since configuration files are quite large, I didn't attach complete dump or radius -X ,
let me know what other info is needed.
