    Did you check what edit strategy is used for the model ? If it's OnManualSubmit then you have to submit your changes

      I've checked that and tried them all without success. After calling insertRecord() I can see the row was inserted in memory but just not saved to disk, ever. Is there anyway to flush it to disk?

      I even switched over to QSqlQuery instead of using QSqlRecord and QSqlTableModel and had the same result. Could this be a linux issue somehow? As I mentioned before I only see this behavior on the first boot off a drive. Works like a charm after that.

        And if you remove the QSQLITE_ENABLE_SHARED_CACHE option ?

          Problem exists with or without that option.

            Can you create a minimal compilable example that shows this behavior ?

                What's the best way to post this? Can't add attachments and it's a lot of code to post in a reply.

                  You can use e.g. "pastebin":http://pastebin.com

                    In that case check "here":https://gist.github.com/snow45/61cea39423b79c61e10f

                    Remember I only see this behavior with the setup initially described.

                      I found the problem. I used the command lsattr to look at file attributes on my database files and found that when I opened App 2 for the first time I was deleting the shared database out from under App 1 and recreating it. Just had to fix that and everything works like I would expect.

                        Out of curiosity, how was it doing it ?
