Description

After a mythbackend restart EPG is not loaded anymore and see the following messages:

Before the restart mythbackend was in the middle of an active scan.

A little bit ugly is also the message when doing an active scan, that it shows it is doing a passive scan:

(StartPassiveScan) - EITScanner (31): Started passive scan

As an intermediate fix:

delete from eit_cache where status=1;

Please ignore my remark about the ugly message. StartActiveScan? scans all mplex, a channel is tuned and EIT is scanned passively until moved to the next mplex.

During ticket creation I forgot to set the Component, please move it to "MythTV-EIT".

I encounter the same problem where, after stopping the mythbackend, select * from eit_cache where status=1; yields all channels locked and EIT/EPG is not updated anymore. The intermediate fix temporarily resolves the issue and EPG is fully updated in minutes until the next day.
