The only ignored state is <c>gc</c> and a process is considered to have - its previous state through out the entire garbage collecting phase. The main reason for this, is that our - model considers the <c>gc</c> as a third state neither active nor inactive. - </p> - <p> - A waiting or suspended process is considered an inactive process and a running or - runnable process is considered an active process. - </p> - <p> - Events are collected and stored to a file.

The matching rules aims to verify that there is at least + one of the Reference IDs that matches one of the Presented IDs.

It is only the + CN (Common Name) that is used by hostname verification. The two other (C and O) is not used + here even when they contain a domain name like the O part. The C and O parts are defined + elsewhere and meaningful only for other functions. + </p> + <p>In the example the Presented IDs are <c>example.com</c> as well as hostnames matching + <c>*.example.com</c>.
