Comment (by hjheins):

 Please find attached the debug log.
 This happened after upgrading a Debian Wheezy to Debian Jessie install on
 the server (ejabberd).
 For some reason the installer leaves the pem file alone, which created the
 issue. Had the upgrade also reinstalled/changed/upgraded the pem file, all
 would have been well.
 The solution in the end was to run dpkg-reconfigure ejabberd to generate a
 new certificate.
 After this, the system ran perfectly again.
