Official server 3528 PVE constantly crashes during purge

I have been attempting level 9 purges and when I do the server crashes I lose materials and thralls while it resets. I didn’t have this issue with lower level purges. I have also had a long-standing problem with falling through building structures and getting stuck. The best way I have found to fix that is to remove my bracelet and then summon my corpse. I would like to know how these issues can be fixed.
