After reading another bug report about replying to large threads with the quick reply box I decided to merge many threads on my test import server so I can test out the authors report. What I found was the following:
- When merging around 20 small (ish) threads with less than a 1000 posts in each thread I would experience a gateway timeout. Looking into it I see that the timeout occurs due to the bundling of the merge threads and the replace into the XF search table. Could this be split into seperate requests?
- When merging around 5 threads with excess of 10,000 posts in each thread I simply get a blank page indicating PHP exhausted it memory. The logs confirm this, memory limit is set to 128MB.
