Update: Its Not the RAM drive causing the issue. I have now taken the save off the RAM drive and restarted the server. Within 10 minutes of doing so, a player reported their blocks had transformed into hydro bays. The server logs show the same "share violation" and "access denied" errors on the blocksmap.dat file as before. Attached is two epb files, one from before transformation and from after. Attached are the latest server logs from after the save was taken off of the RAM drive. The player reporting the problem is Quilue He was in the Zanpumah sector The transformation happened right after warping to Akua and back again. The effected structures we're not in use but we're parked at his base. I am searching for processes or anything that might be locking the blocksmap.dat file via procmon and resource monitor but so far nothing has come up.
