--- Comment #3 from David <ticedo...@hotmail.com> --- Update: I checked the descriptions for interactive timeout and a wait timeout. They are related to individual transactions, not the database as a whole. "MariaDB has always had the wait_timeout and interactive_timeout settings, which close connections after a certain period of inactivity." https://mariadb.com/kb/en/transaction-timeouts/ If a new transaction is attempted by the client, it should connect with no problems. Also, today I had this issue crop up in real time - as I was using digiKam I was looking at an album in a collection and was double-clicking on a preview to open it in the expanded view and everything was working fine. After scrolling through some previews and opening and closing them, I picked one to be the Album Thumbnail. The next time I tried to open a preview image to the expanded view, the <Fail to load image> error showed up. >From that point on, the only "fix" was to restart digiKam. And it starts working again. I'm also running btop on the MariaDB server and watching activity. Everything looks normal until it isn't. At that point, btop shows no more incoming connections from the client I am using. After I restart the digKam app on the PC, I see normal activity on the MariaDB server. -- You are receiving this mail because: You are watching all bug changes.
