Package: freeradius
Version: 2.1.10+dfsg-2
Severity: normal
Some times server crashes due to segfault problem. When occurs we can see a
message
like this(*) in system log (/var/log/syslog).
We follow the instructions at /usr/share/doc/freeradius/bugs.gz and
try to 'hunt' the segfault, because it occurs occassionally. The result
was this (**).
We will provide more information about the configuration and architecture.
Thanks.
