There was one similar case recently. The problem occurred when radiusd was sent HUP after configuration change. > Briefly stated, at some apparently-random point the radius server > attempts to reconnect to the back-end ldap server, but the connection > fails with "Undefined subroutine &main:: called at > /usr/share/perl5/IO/Socket/SSL.pm line 391." Yes, this was the same line where the problem occurred previously. We got the same backtrace. This line in IO::Socket::SSL 1.53 as shipped with Ubuntu 12.04 tries to call Net::SSLeay::connect() but fails. During debugging IO::Socket::SSL was updated to the latest version, but the problem persisted. I think the solution was to use restart instead of HUP after reconfiguration. The problem was seen on RedHat 6.2 with locally compiled Perl 5.14.2. When I tried to reproduce the problem I could not do it successfully. I also tried Ubuntu 12.04 but that did not help. Do you see the problem when radiusd is HUPed or does it happen when there's a need to reconnect to LDAP server for some other reason? Also, one idea we discussed here is to try upgrading Net::SSLeay. Can you try compiling Net::SSLeay locally and try the latest version? It does not look like a Radiator problem and with IO::Socket:SSL the problem was seen always when Net::SSLeay::connect() was called. It would be a good idea to see if upgrading Net::SSLeay helps.
