New installs die after a few days ruuning fixes/0.27 (v0.27 (v0.27.5-71-ga62fc0d) with all updates per ticket #12611. System built on January 18th works correctly until January 21st. Symptom is- after scheduling and recording over days suddenly Media Library-Watch Recordings shows no recordings available. Backend log shows backend is continuing to record previously scheduled programs. Only backend error message around that time is:

Jan 21 13:47:00 mythbuntu64-2 mythbackend: mythbackend[2315]: E MythSocketThread?(73) mythsocket.cpp:745 (WriteStringListReal?) MythSocket?(2603380:-1): WriteStringList?: Error, called with unconnected socket

Frontend errors around that time are:

Jan 21 13:45:38 mythbuntu64-2 mythfrontend.real: mythfrontend[2359]: E ProgramInfoLoader? remoteutil.cpp:184 (RemoteGetRecordingList?) RemoteGetRecordingList?() list size appears to be incorrect.

Memory usage seems high:

Livetv continues to work fine.

A remote frontend running an earlier version connects to this backend and also shows an empty media library.

This symptom has occurred on multiple install attempts on different hardware with various tuners.
