I recently set up a discourse, and migrated content from a phpbb3 forum.
We actually migrated jost some topics/subfora, which means that after a full import, we deleted lots of categories again, to only keep the subfora that got split out. Deleting those postings and categories happened immediately after the import.
Now, after that import, sideqik showed around 100k jobs that needed to be processed. After a couple of days we are now at 500k processed jobs and around 165k still to process.
So they get processed, but it seems every X hours, another batch of around 100k jobs get created. It does not seem like this will get purged eventually.
Is this normal behaviour? Can the deletion of messages be part of a problem here?
Better than having some providers (or your own) blacklist you. We had this happen when we went live. The first couple hours or so were a bit hectic until we figured out what was going on.
Basically we were sending a digest to every single user. All 39K of them. Given that they all had to reactivate their accounts by sending a forgot password mail while this was going on there was a certain level of… confusion.
