We have run into an issue on several of of our Debian servers after upgradeing to Wheezy. The issue is one that tends to go unnoticed for a while, until you are looking through the files in ‘/var/log’ and notice that none of the files have updated entries since the date of the last upgrade.
The solution to the issue is to install the following package:
‘apt-get install inetutils-syslogd’
After installing this missing package, syslogd should once again be running, and you should start to see new entries show up in your messages, syslog, etc files.
