Vaultwiki breaks sitemap generation process, caused server to run out of disk space and crash
Was woken up very early this morning by my alerts going off that our sites were down.
Eventually tracked it down to Vaultwiki breaking sitemap generation during the tags step. When it took down the server, it'd created 43GB of temp sitemap files, when that's normally < 10MB. It would have continued to try to generate the temp files except it ran out of space. The sitemap log shows it created 8,202 files tracking 410+ million urls on a site that has nowhere near that.
I just now implemented the fix for the 'Undefined Index: user' issue, hoping that would fix this as well but it didn't...
When I run build sitemap with Vaultwiki disabled, it works perfectly. But as soon as VW enabled, it just perpetually churns out temp files.
I've disabled automatic sitemap generation for now. Let me know the fix and I'll apply... I'm kind of surprised no one else has hit this yet.
