502 errors when renaming large (by topic count) categories

[SimeonGriggs]

Thanks … but these tail'd logs are going a million mile an hour, I don’t think I’ll catch anything

Just trying to rename one category gives a 502 error every time.

Just a correction about this: I think I previously did Category.where(id: 21).update(name: "General") for a category from which I moved the topics out or something like that, because I had to use this command multiple times on various categories right now, and it appears that the command duration is proportional to the number of posts in the target category. So basically, it’s the same issue as when I update the category from the interface, except that it won’t timeout in the command line. It…

It looks related to the search stuff? That will indeed be very costly and should be moved into a background task.

Hope not, I fear there are already too many of those.

My server-side backups keep failing because even though they’re running at 2am (local time for the majority of users) there’s too much disk activity for it to complete.

…but I don’t want to get this off topic

@tgxworld can you kick all the search work including setting version to 0 to a background job?
