I manually upgraded Net::SSLeay on Ubuntu 12.04 as follows:

   # Check current version
   perl -MNet::SSLeay -e 'print "$Net::SSLeay::VERSION\n"'
   # Bring in build dependencies
   aptitude build-dep libnet-ssleay-perl
   # Follow defaults when running cpan
   cpan Net::SSLeay
   # Check post-upgrade version
   perl -MNet::SSLeay -e 'print "$Net::SSLeay::VERSION\n"'

The default was version 1.42 installed in /usr/lib/perl5/Net, and the 
upgrade was 1.48 installed in /usr/local/lib/perl/5.14.2/Net.  I still 
had a crash with HoldServerConnection enabled, but it appears to be 
stable without HoldServerConnection.

Thanks for the suggestion to upgrade Net::SSLeay, this allowed us to 
return to stable operation.

Cheers,
