An unchecked memory leak in Firefox caused my RAM to fill up completely, leading to a number of pretty hairy error messages from various programs. Among them was a DOPUS crash message, which I sadly was not able to record. After managing to do a clean restart, DOPUS launched on startup as normal. However, it was just the default lister without any of my tabs. Under Settings > Startup, "Open the Listers that were open when the program was last closed" is selected, and "Backup open Listers automatically every 20min" is checked. I've looked in Tab Groups, Lister Layouts, and the Backup and Restore dialog, but can find no such auto-saves.
I had many tabs open, far too many to remember. I really don't want to lose them. Is there a setting I'm missing? Is it a bug? Thanks in advance for any help.
If the system completely runs out of memory (including virtual memory / swap file) like that, all bets are off. There won’t even be enough memory to save the backup and the whole process (and many others) will probably be terminated in a random state.
The tabs in question were open for about a week; wouldn't they have been included in the last successful 20min backup? If not, I guess I don't really understand the point of the "Backup open Listers automatically every 20min" option; how it differs from the "Open the Listers that were open when the program was last closed". This tab-loss-from-memory-leak problem has occurred at least 3 times in the past year, and I was really hoping v13 would solve it.
Possibly, but possibly not, if the last backup was done when there was so little memory it failed to save a valid file.
When memory gets that low, it's basically game over. Nothing will work properly, even parts of the OS itself are going to fail in strange ways.
Completely running out of system memory is very rare these days. There are lots of other ways that a process can crash where the backup helps.
I would worry about the Firefox memory leak instead. That should not be happening in the first place, and is going to take out a lot more than just Opus, and seems like a much more pressing problem than having to re-open a few folder tabs.
