[LON-CAPA-admin] loncontrol not starting

Hello All,

I just built a new VM to take over as lon-capa.bsu.edu. I tested everything on it and everything seemed to work. We just cut over the DNS to make lon-capa.bsu.edu point to the new VM. And I rebooted the system to give us a "clean" start with the new DNS.

Now I can't connect to the system using https://lon-capa.bsu.edu so I connected by ssh to the box and found that neither httpd nor loncontrol was running and when I try to start loncontrol, I get the following error:

[root at lon-capa01 ~]# /etc/init.d/loncontrol start
Opening firewall access on port 5663.
Port already open for 128 IP addresses
Starting LON-CAPA
Starting LON-CAPA client and daemon processes (please be patient)
/usr/bin/perl: symbol lookup error: /home/httpd/lib/perl//tth.so: undefined symbol: Perl_Gthr_key_ptr

What's going on here? Everything was working yesterday and this morning, but now loncontrol won't start and we have a dead lon-capa. Any idea what tth.so is and why are there **two** slashes in the path?
