This limit has existed for a long time, but I'm only describing it now because I didn't actually expect people to run into it.
SymptomYou'll get this rather non-descriptive error message when editing something:
Database Error
Please try again. If you come back to this error screen, report the error to an administrator.
The edit will not happen, but will be saved as a draft.
CauseYour post's edit log is taking up too much space. The space it takes up is related to
total_bytes_of_post * times_edited_per_week, though it's not quite a linear relationship due to compression. A maximum-sized post can be updated maybe 5-20 times per week before hitting this error.
SolutionsSolution 1:
- Wait up to a week for the system to archive your post's edit log. This currently starts every Saturday at 20:51 UTC and takes around an hour to complete.
Solution 2:
- PM me with a link to your post and I'll fix it manually.
- I'm probably not going to do this more than once per person per year or something.
In either case, you'll need to reduce either or both of the size of your post or the frequency at which you update it in order to prevent this from happening again.
Maybe in the future I'll try to eliminate this problem. It's caused by the kludgy way I implemented edit logging.
