Fully opening the directory failed to fix the issue. So in summary the program works for days then dies with this in the log:
(14) cannot open file at line 28488 of [f5b5a13f73] (14) os_unix.c:28488: (24) open(/usr/share/cm160) - (14) cannot open file at line 28488 of [f5b5a13f73] (14) os_unix.c:28488: (24) open(/usr/share/cm160) - (14) cannot open file at line 30285 of [f5b5a13f73] (14) os_unix.c:30285: (24) open(/usr/share/cm160/eagleowl_stat.db-journal) - (14) statement aborts at 29: [UPDATE energy_hour_stat SET status = 1 WHERE record_count = 60] Any advice on what could be causing this?
