Hello Alan, And thanks for the reply. If you mean that my customhooks perl scripts for rlm_perl deals with any threads then no. If you mean that our compilation of perl which was installed with from apt-get is compiled in a strange way..Then I have no idea what.

Hi, And thanks for the reply. If you mean that my customhooks perl scripts for rlm_perl deals with any threads then no. do you deal with all file handlers, database handlers etc in your code cleanly... or do you just ditch them? the PERL module will be called at the same time by many FR threadsso unless you make the script resident then you'll likely to be facing issues. either way, at least follow docs/bugs and get the gdb output for when things go wrong alan - List info/subscribe/unsubscribe?

Debian-built perl (installed in /usr/lib/perl5) tries to load DBI module from locally built perl (installed in /usr/local/lib/perl). It's a bad idea. Try to install debian-built DBI module (libdbi-perl) and use it. I think the same error (mashup of multiple perl builds) was encountered by Johan Meiring. Debian-built freeradius uses debian-built perl. So only debian-built perl modules can be loaded by rlm_perl. You can easily test your debian-built perl supports loading of DBI (and so debian-built freeradius): /usr/bin/perl -e \ 'use DBI; print join(\n, DBI-available_drivers), \n;' - List info/subscribe/unsubscribe?
