Another source of information about a problem is documentation about known errors and
the knowledge base.
Information about already known issues can be found in two places: the Known
Errors module in the Problem Management application, or in the Knowledge
application. The Known Errors module filters the problem table to
present all of the problems whose cause has been identified but cannot be fixed. The knowledge
base may have information that was gathered from incidents, and may also have useful
workarounds for problems.
