Well, I’ve triangulated the error. It is definitely related to the database size hitting the defined limit.
Once the database hits the limit set (mine is 7Mb) in the &advanced preferences screen, the error appears. It periodically comes and goes as Mint must decide to trim the database as it exceed the limit. I was ‘fixing’ the error before by uninstalling and re-installing Secret Crush.
If I set the limit to something smaller, the problem continues and exhibits the same behavior. If I increase the limit, after 15 min or so the problem goes away, only to re-appear once again when the database limit is reached.
I can re-produce this at will. If I just set my database size to a smaller number than the current database the error shows up fairly soon.
Long ago I migrated from Bluehost to Mediatemple and I was one of the early folks who ran on x64 bit machines had issues regarding signed and unsigned variables. The exact problem escapes me now.
Is there anyway I could manually check the SQL tables for proper settings? Perhaps the initial setup and subsequent migration flipped a bit somewhere?
