In System Center 2012 Configuration Manager, when you use the CMTrace log viewer to review any log that contains a line exceeding 8000 characters, the log is truncated at that line.
There are two workarounds to this issue. First, you can simply view the log file in Notepad. Viewing the log file in Notepad will allow you to see all of the contents. Second, if you prefer to view the log in CMTrace you can edit the offending lines in Notepad (making them less than 8000 characters long) and then view the edited log in CMTrace.
