I've dug through the system logs and nothing, I've manually looked in the database and they do not exist. We think it was too posts. The thread even has someone thanking the guy for his post but none of his posts in that thread exist any more. Other posts in the thread are fine, his other posts are fine. I've had no other reports of missing posts so far. xf_posts reads around 1.6 million posts which sounds about right. Any ideas what happened? It seems to coincide with a db repair I did so all I can think is his posts in that thread were somehow corrupted and got purged. Not sure, but if it happens again I'll be extremely worried.. I have an 8core dedicated server, no reported issues lately other than this. Thanks!
